 Posted: Wed Jan 24, 2007 11:55 pm Post subject: [SOLVED] Kernel panic on boot: IO-APIC error |
 |
|
When I boot my Gentoo box, it says
| Boot log wrote: | .. MP-BIOS bug: 8254 timer not connected to IO-APIC
Kernel panic - not syncing: IO-APIC + timer doesn't work! Try using the 'noapic' kernel parameter. |
If I boot with the 'noapic' parameter it works fine, but I assume that APIC is a good thing. (Besides, errors annoy me.  )
I have and Asus M2N-SLI motherboard with an nForce-MCP55 chipset and an AMD Athlon64-X2 processor. I'm using gentoo kernel 2.6.18-hardened.
I assume there's a kernel module I have to turn on, but I can't seem to find it.
Here's my lspci output relevant to the chipset, in case that helps (I left out the lines about IDE, SATA, ethernet, USB, IEEE 1394, and audio).

| Thank you. Upgrading to 0807 fixed it. |

If your BIOS isn't patched, and none is available, the kernel now handles MCP-55 timer issues with acpi_use_timer_override. While not applicable to this motherboard in particular (since the mfgr patched the BIOS and you don't need the switch) other NF3-5x/MCP-55 boards are EOL'd and no longer supported with bios updates so the issue persists.
noapic/irqpoll binds all interrupts to one cpu. While it stabilizes the kernel it's not the optimal solution. With the acpi_use_timer_override switch I'm getting interrupts on both CPUs though CPU1 is favored (which is ok), and I'm stable.
here's the kernel.org bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=8368
Thought I'd throw this in since I'm in this boat (MCP-55, no bios update).
