hard locks in 9.2


I have a strange problem I can't seem to remedy. I have mandrake 9.2 and at random times I get hard lock ups. Nothing will respond, no keyboard commands work. If I hit the num lock key the light does not go out so the kernel just said "to hell with this i'm outa here." I re downloaded mdk9.2 isos today, checked the checksums to make sure they are ok, and burned them. This did not help as I thought my isos may have been messed up the first time. I dual boot with Windows XP and I have no problems at all with it. I did have red hat 9.0 installed also and again, no problems with that either. But I DO have mdk9.2 problems with hard locks. Recompiling the kernel does not help either. I really like mandrake 9.2 and I'd love to fix this some how. Any suggestions? Thanks.

It could be bad memory, I've seen that mess up several Linux systems.
If you have the time and bandwidth, it might be a good idea to download Knoppix, burn it to a CD, and then leave it running overnight. In the morning, check to see if it locked up or not. That will tell you if it's something to do with Mandrake not liking your hardware, or if it's something entirely different.

You know I have this problem as well. I can't figure it out for the life of me. I've reinstalled, recompiled, and can't seem to figure it out. It happens on 2 diffrent machines, both with similar but diffrent hardware configs. Both machines run fine under windows or any other OS.

Symptoms are as described above. The system hardlocks randomly. Sometimes after 20 mins, sometimes after 20 hours. It happens while using apps, and while not. It does not seem to have any rhyme or reason. At one point I thought it might be DPMS or some sort of power related thing, because I had disabled it and the box didn't hardlock for over 24 hours, but then it locked later that morning after I had come in.

If anyone has any ideas I'd be happy to entertain them.

ASUS & Hard lock ups

I've had similar results with the ASUS A7N8X Deluxe mobo. From recent testing, I've come to believe the Hard Drive chipset/drivers are the cause. Here's a copy of a recent post to a linux email list I belong to:

Hi all,

I've had random hard lockup problems with a self built PC for a long while now. It's getting to be a real PITA, as it managed to wipe my root partition out this past weekend.

Requisite info:
ASUS A7N8X Deluxe mobo
AMD Athlon XP 2800+ (barton 2.083 GHz)
1 Gig Ram
MSI nVidia GeForce FX5200 Video Card
Primary IDE Channel : 60 Gig HD (WD I think) & 52x CD-Rom
Secondary IDE Channel: 20 Gig HD (also WD I think) & 24?x16?x52x CD-RW
OS - I don't think it matters, Mandrake 9.1 until the crash this weekend claimed the root partition, then Knoppix CD received at latest install fest after that, it's also locked up when running the new Novell supplied SUSE distribution that I installed at the install fest on a 160 Gig Harddrive. I could also test with Win2K some more, but haven't yet...

Symptoms:
Locks up hard - no keyboard/mouse response at all, reset or power button to reboot.

Troubleshooting steps taken:
First off, heat is not a problem, system is water cooled, processor temp monitored by 2 sensors, one built into mobo, the other probe, which is mounted next to the processor, is connected to a Digital Doc 5. From all the readings I've taken, no part of the system has ever gotten above 100 degrees Fahrenheit. A DigDoc5 monitors 8 locations, I'm monitoring incoming air, video card processor, memory, northbridge heatsink, processor, drive area, power supply and something else I can't remember off hand. (typing at work, machine's at home)

Ok, so I first thought RAM was the problem, but I've swapped that a few times, and run memtest a bunch. No lock ups during that process, and the memory tests are clean. I also thought maybe it was driver issue with Mandrake until the CD version of Knoppix exhibited the same behavior. Also used to think it might have been the USB mouse/keyboard, but swapping those for PS/2 mouse and keyboard didn't make any difference.

So, once the crash ate the root partition, I booted up with the Knoppix CD to attempt a fix, it was toast. Then, I tried to reinstall Mandrake, got mostly finished but then it Locked Up. I rebooted, seemed to be fine, started configuring, had another lock up, this time it ate Perl, and thus wouldn't let me into X-Windows. So, I abandoned that and began to only troubleshoot.

I again grabbed the Knoppix CD, booted it, and ran the memtest program for about an hour. No lockups, no errors. No subsequent memtest runs ever resulted in a lock up.

Now, for those who are not familiar with the Knoppix CD, it is an entire linux installation on CD, when it boots it creates a RAM drive to store the various things like /etc /home etc. So, there is no hard drive involved when it first comes up. This is important because as long as I left the hard drives alone, the machine was stable and running well for hours at a time. I did that to search the net for other descriptions of problems similar to mine, and I ended up upgrading my BIOS during that search. The BIOS update didn't help at all, but also didn't hurt anything either (that I can tell).

Once I got the hard drives involved, that's when the machine locks up. I started testing the first hard drive thinking there might be some bad blocks. Now to be totally fair, I was able to get a random read/write non-destructive test of the root partition to complete 2 or 3 times. However, it was the 7 to 10 times that the random lockups happened during this process that has led me to believe that the mobo chipset or linux drivers for said chipset is the real culprit. I ruled out the actual hard drive by also testing on a blank partition I had on the secondary 20 Gig HD, and it locked up during that test as well. BTW, no bad blocks were ever found on the Hard Drives.

I'd also thought about conflicts with the CD drives, so removed the CD-ROM drive that was sharing the primary channel with the 60 gig HD. Didn't matter. It still locked up.

So, does anyone have any suggestions of what more to test? Or maybe what program to use under windows to really stress test the Hard Drive/controller?

Thanks,

-Scott

random hard lock ups on nforce2 chip set mobo?

I've spent the past 4 days nearly solid working on and looking for help on my particular hard freeze problem on an ASUS A7N8X Deluxe mobo.

While I had dug deeply enough to think that it was an IDE problem because I could reproduce the problem by 'fsck.ext3 -vcc /dev/hda1' after booting off of a knoppix linux on CD, it turns out the problem is with timing of interupts etc with the nforce 2 chip set and the linux kernel.

See the following link for a better description and links to patches and work arounds:
