Asus M2N32 Ubuntu Dapper Drake Kernel Panic upon boot
I am trying to set up a nice little dual-boot configuration on my computer between Windows XP and Ubuntu 6.06 LTS (Dapper Drake), but I keep running into headaches. The system configuration is as follows:
Asus M2N32 SLI-Deluxe Wireless Edition
Athlon X2 4600+
2gb Corsair XMS2
SoundBlaster Live 5.1 (I love the emu10k1 compatibility in Linux)
Immediately upon bootup of the Ubuntu Dapper Drake LiveCD, I am faced with a kernel panic and the error message:
MP-BIOS bug: 8254 timer not connected to IO APIC
I looked for the error on Google, and it appears that a lot of older SMP motherboards had the same problem years ago. I can make the system boot by supplying the kernel arguments "noapic" and "nolapic," but the system only sees one of the two cores that way. Also, when running the closed-source NVidia drivers, the system has about a 50% chance of hard-freezing when you switch from X to a system console (using Ctrl-Alt-Fkey). I don't know if those freezes have anything to do with the APIC issue, but my intuition tells me it probably does.
I flashed the bios to 0903 (latest version as of the time of this writing) in an attempt to fix it, but I get the exact same error as when I was running 0603.
Does anyone have any suggestions on things I could try to fix it?
I have used the ASUS M2N32 SLI Deluxe motherboard fine with Fedora Core 6 -- though I hadn't tried it against the newer motherboards. Though I have successfully used the noapic and noacpi arguments previously on other motherboards with similar problems.
Have you tried updating your kernel?
I take it you see only one of the cores by cat /proc/cpuinfo If you are only seeing one core, an SMP kernel needs to be installed or compiled from source. I thought Edgy Eft had used an SMP kernel by default (are you using the 32-bit or 64-bit version?).
Do you have Composite enabled or any other information as to your NVIDIA configuration?
I'm using the latest stock 32-bit Ubuntu 6.06 kernel (2.6.15-28). I currently don't have my NVidia driver installed so the machine won't crash all the time, but when I had it installed I was just using a very basic setup with no frills.
I'll give the 64-bit LiveCD a try, and look around changelogs and such to see if there's any record of a fix for problems like these since the release of 2.6.15. Thanks!
Yeah that's a common problem with older kernels (I have the same board and problem). 2.6.19 was supposed to add better support for AM2 boards, but I am not exactly sure what module needs to be compiled for that to happen.
