Most recent kernel where this bug did *NOT* occur:n/a Distribution:ubuntu-feisty-edgy knoppix 5.5.1 Hardware Environment:ASUS M2A-VM latest bios.. Software Environment: Problem Description:Tried on Knoppix, Feisty, etc.. every livecd distro.. the amd 690G / SB600 chipset(Asus M2A-VM latest bios=0402) isn't compatible for some reason and locks up during hardware detection... have sought support from AMD, Asus, Ubuntu, Knoppix etc... no one seems to be able to help. Steps to reproduce: insert any livecd on an AMD 690G SB600 motherboard
I can get it up and running with a 64bit kernel...(i.e. feisty AMD64) however its still a no go with the 32bit...
Ubuntu feisty kernel (2.6.20-generic) and one 3rd party kernel I've tried works, I'm trying to investigate what patches/config options are responsible.Vanilla 2.6.20.7 crashes. Booting with 'acpi=off' fixes kernel crash but my USB keyboard no longer works, making the system unusable.
thanks for the tip with the acpi=off but I have the same issue.. I have usb mouse and keyboard :C the 64bit kernel seems to work great... go figure... I am a little leery of running 64bit as I have heard horror stories of instability.. incompatibility etc... thanks again for the help
OK, after looking through this I found out that vanilla 2.6.20-rc5 boots fine. The cause of this bug must have been introduced after this (I may try -rc6 to see if that works since we already know 2.6.20 final crashes). There's this line in dmesg: "ATI board detected. Disabling timer routing over 8254." I'm not sure if this check is present in later kernels, if not this may solve the issue with AMD 690G/M2A-VM motherboards.
B, Thanks again! Since you have already tested 2.6.20-RC5, do you want me to test RC6 and up? I will see what I can do about recompiling these kernels into the ubuntu livecd...
Matt, Sure, test -rc6 if you can. Also, I've tried 2.6.19-gentoo (the distro I'm on) and it crashed but I didn't try 2.6.19 vanilla. It would be interesting if older kernels crashed too. It would also be helpful if you have a decent digital camera to take a picture of the kernel crash backtrace. I have a pic I took with a camera phone however the text isn't very legible.
yes I have tried some older versions they seem to crash also...

I am having some trouble recompiling the kernels for use in a livecd... do you know a good tutorial... I would really love to help squash this bug :)
AHA!!! I found the culprit causing this bug... If you Disable HPET (High Precision Event Timer) in the bios... the newest ubuntu feisty works great... however if it is enabled it locks up... hopefully this will be addressed in the future... but I can live with this workaround..
This appears to persist in 2.6.21.
Upgrading the BIOS on ASUS M2A-VM to latest version (0601) solved the problem for me. (Works now even when the HPET is turned on) I have problem with PCI devices on this motherboard thought.
Updating to bios rev 0601 does NOT solve this problem on my machine, as it still hangs on bootup.
Just to be clear, with recent kernels (2.6.21.3) and newest bios (0601) the crash no longer occurs during hardware init but instead happens on my machine when the init scripts/udev load the usbhid module. Disabling HPET in the bios allows the machine to boot normally.
This bug appears to be fixed with latest BIOS version 901. I've tested with kernels 2.6.21.6 and 2.6.22, both boot fine with HPET enabled on BIOS version 901.
good to know it's fixed in BIOS update. maybe a dup of bug# 6975? anyway, mark it as wontfix..
