M5a97 R2.0 16GB Slackware 14.0 kernel panic?


Hello,

I am having trouble getting my system to be stable - locks up on me. I'm installing Slackware 64 bit 14.0 on a newly purchased M5A97 R2.0 motherboard with an AMD FX8320 CPU. I also installed 16GB of DDR3 1600 RAM.

Since my system freezes, I can't capture the screen message - here's my attempt to type the message I get in. I've looked it over closely, but there still may be typing errors:



INFO: rcu_bh detected stalls on CPUs/tasks: { 3} (detected by 7, t=14642594 jiffies)

This message will regenerate with mostly the same numbers about every minute or so.



So, I'm doing a completely fresh install - starting with fdisk. Install goes fine each time. When running - varies how long my system will run - from minutes to almost an hour. I've rebooted and checked the BIOS CPU temp - around 110 degrees F. Motherboard temp is about 85 degrees F.

I've tried typing in some of the error message info into google - haven't got far.

My hard drive is brand new; moreover, I tried another new hard drive.

I have 2 PCIe 2.0x16 slots - one is x16, other is x4 - tried both with 2 different video cards. One video card is known to be working on another system.

I've tried ext4 and ext2 file systems.

I've put the latest motherboard BIOs in.

Any help would be greatly appreciated.

First to mind is trying to kernel disable cpu idling, with:
Code:
cpuidle.off=1
Another possiblity to try is to disable APM Master Mode, C1ESupport, and/or C6State in bios settings.

Looking at your call trace, this is the direction I would start working from.

YMMV

<edit>
Also, are you doing any overclocking? I just read on an overclocker's forum that that mobo is no very
robust for that. Though, I suspect that since the idle timers seem to be related to your issue, this
may not be the issue.

You do realize this is a Uefi mobo?
I'm prettysure that slack cn handle it but if you're not ready you need to change settings in bios to legacy

Thanks for the replies.

I went into BIOS (or UEFI?) and checked:

APM (no changes)
ErP Ready Disabled
Restore AC Power Loss Power Off
Power On by PS/2 Device Disabled
Power On by PME Device Disabled
Power On by Ring Disabled
Power On by RTC Disabled

CPU Configuration
Cool 'n' Quiet Always Enabled
C1E Enabled (set to disabled)
SVM Enabled
Core C6 State Enabled (set to disabled(
HPC Mode Disabled
Apm Master Mode Auto


Also, I am not overclocking. My system will spend most of it's time in idle waiting as a print server, but I do want the speed/power when I'm using it at nights.


For the reply

I'm not sure how to do this - what would be considered legacy settings? I did set the BIOS back to defaults when I first started, but I don't think that is what was meant.


With changes in place - running in X with MSN doing it's thing - so far so good. Will I take a big heat in power savings disabling those 2 features? I'll post later on results after running longer.


Thanks.

You'll have to read your manual or make sure that the distro you use has efi support on the installation cd/dvd.

The M5A97 (like most other ASUS mainboard) will automatically switch to legacy mode when it detects that the medium you start from is not UEFI capable, so this shouldn't be your problem.

Update: Let it run all day - still ok when I came home. Went out to do some things and when I came back CAPS LOCK and SCROLL LOCK were flashing and system unresponsive. Rebooted and went into BIOS - CPU temp about 110 degrees F and Motherboard temp at about 90 degrees F. Finished reboot and started X - ran for about 2 minutes and got kernel panic:

Each line begins with [ 103.673021]

I didn't get the repeat of this message - only happened once during the 15 minutes it took me to type this in.

Thanks.

<edit>

I enabled APM Master Mode again - still running. I'm going to see about finding a memory checker/burn in program.

<edit>

Crashed again - when I came back and tried doing stuff in HMI.
This time (I'm just going to type the words)

This time you got some pagefaults. I would recommend to test the RAM using Memtest86+.

If you have errors on memtest, that would exaplain at least some of the problems. Even if you pass memtest, I'd try downclocking your RAM from 1600 to 1333 or 1066.

I'd also check your BIOS/UEFI version. There are a lot of updated versions with 'Improve system stability' entries.

You should find your BIOS/UEFI version in the inital screen in 'ezy mode' or on the 'main' tab in 'advanced' mode. It should be some 4 digital number, e.g. 0208.

Giving Up on Slackware 64

I ran Memtest86+ for over an hour with no problems. I've run the Ultimate Boot CD and could only get my CPU up to 50.2 degrees Celcius. Video checked out ok. Already flashed the BIOS to latest and tried 2 new hard drives. I guess my next step is to try another Linux - thinking Debian since that is what is on my Raspberry. See if that works.

With the CPU at 110 degrees, you should turn off. Maximum junction temperature is about 150, and given the way things work, some bits could be up there when you see 110 degrees.

My guess is that acpi is misbehaving. Are the fans clear, and are they howling? They should be. The m/b is also too hot.

110F (about 43C) is not at all a high temperature for a this kind of CPU, I would be worried if it goes indeed to 150F, but for now it doesn't seem that to high temperatures are the problem here.

Of course these temperatures are not too high. My reason for posting them was my first thought with these types of errors is heat.

My conclusion is Slackware doesn't fully support this CPU and/or this motherboard. I read the history of Slackware and didn't realize that AMD processor support wasn't added till recently (release 13). Couple that with a relatively new AMD processor and one could anticipate challenges.

I am now using Xubuntu.

Yeah, 110F is ok. Who ever uses F when the bios stuff reports in C? Obviously this OP. Completely threw me.

Slackware runs just fine with AMD CPUs for ages, what was added with release 13 was official 64 bit support. I run Slackware on two AMD machines (laptop: Athlon QL-66 + AMD 780GM chipset, desktop: Phenom II X6 + AMD 990X chipset) without any problems.
