Hello,

I am trying to install RH9.0 on a HP Pavillion 522n. The installation goes just fine until the machine reboots at the end. While loading the linux, everything goes fine until it gets to the point where it says

IDE0 probing (hex address) on IRQ 13
IDE1 probing (hex address) on IRQ 14

It may be IRQs 14 & 15, can't remember exactly, when the machine just reboots (this is why I don't have the hex addresses, they're gone too quickly). The installation attempt before this one actually froze at this point and required a hard reboot. The boot disk made during installation does exactly the same thing.

I seem to recall that the motherboard uses IRQ sharing, but don't know if this is a problem. I tried disabling the secondary IDE controller from the BIOS and it got to the IDE0 line, didn't print the IDE1 line (duh) and rebooted.

Unfortunately, I now have no internet connection at home, so can only check this at work. Any help would be extremely appreciated and any other info I can give will be given, although there may be a lag of a day or so.

Tonight I will try booting in interactive mode, just to see what I can see, and will check back tomorrow.

Thanks,
Will

I don't have a solution, but this sounds identical to the problem I just posted. Mine is HP 752n, but same symptom, system gets past some hardware stuff and reboots again.

As I posted in reply to myself, I later learned that turning off PnP stopped it from the reboot. It just STOPS when it gets past the IRQs. I foudn I can do a rescue boot from the install CD, but that just gives me access to command line in Linux to get at the install. So I am still stuck, too. If you learn anything, please let me know and I will do the same. I suspect if one of us solves this, it will solve it for both.

I found the problem on mine, and given your system model, wouldn't surprise me if yours is the same.

On the boot command, I needed to use the option:

apm=off

I was using a boot floppy, so I added apm=off to the linux startup command in the .cfg file to keep this change.

To try it out, when the system gives you the boot prompt, type:

linux apm=off

Or if you are already giving it other parameters, just give it the apm=off as well.

That turns off using power management from the BIOS, which apparently can sometimes cause it to crash.

Good luck, I hope this solves it for you, too.

Hi. A buddy of mine brought over a new kernel (2.5.38) and we installed it and now the system boots. Xwin doesn't work, the log file says:

Open APM failed (/dev/apm_bios) (No such device)

When I go home from lunch, I'll try that apm=off thing and see if that helps Xwin. Thanks for all the help!
