Most recent kernel where this bug did *NOT* occur: None Distribution: Ubuntu Hardware Environment: AMD Athlon 64 3500+ in a Abit KN9 Ultra with MCP55 chipset - BIOS has been updated to last available version (1.6 at this time) Software Environment: Grub and Kernel Problem Description: Kernel Panic without 'noapic' option apic=debug results in (sorry for any errors - this was copied by hand): ENABLING IO-APIC IRQs Synchronizing Arb IDs. ..TIMER: vector=0x31 apic1=0 pin1=0 apic2=-1 pin2=-1 ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up (IRQ0) through the 8259A ... failed. ...trying to set up timer as Virtual Wire IRQ... failed. ...trying to set up timer as ExtInt IRQ... failed :(. Kernel panic - no syncing: IO-APIC + timer doesn't work! Boot with apic=debug and send a report. Then try booting with 'noapic' option I've tried several kernel other versions from distributions (mostly live cd's the last was a live build of Ubuntu) all with the same results. I don't know if it's related or not, but the machine is unstable when booted with 'noapic'. Lost network connections happens several times a day. Sometimes there are even kernel oops. Steps to reproduce: Try to boot the machine without 'noapic' as a bootparam.

Created attachment 10362 [details] dmesg with noapic
Changed the kernel version as the problem is exactly the same with a vanilla kernel 2.6.20. If this is a BIOS issue, could some give me a clue on what to complain about to the manufacturer? Thanks in advance, Jo
Changed severity to match the definition.

Just a note on this: this behaviour was unrelated. The BIOS was detecting the ram as DDR2 533 and it was DDR2 400.
I am trying to boot 2.6.20.2 on a Gigabyte GA-M57SLI-S4 with f7 BIOS AMD Athlon 64 3800+ X2 and got same message: ENABLING IO-APIC IRQs ..TIMER: vector=0x31 apic1=0 pin1=0 apic2=-1 pin2=-1 ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up timer (IRQ0) through the 8259A ... failed. ...trying to set up timer as Virtual Wire IRQ... failed. ...trying to set up timer as ExtINT IRQ... failed :(. Kernel panic - not syncing: IO-APIC + timer doesn't work!
Just for the record - is there specific reason why you boot with noapic, does it boot in APIC mode?
No. As the original report shows, without noapic the kernel just panics.
Looks related to this thread. So far I have had some success with the additional boot parameter 'acpi_use_timer_override' instead of 'noapic'. Are all (or most?) nforce 5xx / MCP55 bios(es?) broken? http://bugzilla.kernel.org/show_bug.cgi?id=8219
The boot trace shows that you have PM timer, so the acpi_use_timer_override might not help. In the code, there is a correlation between NVIDIA timer overrides and presence of HPET timer. Andi, can you advise please?
... and another question: are you booting 32 bit kernel or x86_64? (The cathegory shows the bug is against i386).
No, 64 bit, but I suspect that the underlying issue is related to interaction at the firmware level, which is most likely much more similar then different between instruction sets for the processor. Just because you're running 64 bit shouldn't change PCI* bus relations/interrupts. Don't MSI/traditional interrupts work under both instruction sets? Though I've never written anything at this level for a modern computer, only those really ancient and inexpensive lab boards during a few college courses... so take this with a huge grain of salt.
Michael, I saw your boot trace and it was 64 bit. Joao, you seem to report this under i386, does this mean you are using 32 bit kernel? The timer quirk code is present in both archs, but the code flow is different.
Correct. This bug was reported on a 32 bit kernel.
Even with pmtimer irq 0 is needed (it only is a counter not an own interrupt source) Does it boot with acpi_use_timer_override? If it's like the standard HPET BIOS bug. We have a zillion of dups on that one in the database. Most likely it will be fixed with (against mainline, apply in this order) ftp://ftp.firstfloor.org/pub/ak/x86_64/quilt/patches/early-quirks-unification ftp://ftp.firstfloor.org/pub/ak/x86_64/quilt/patches/nvidia-timer-quirk
Any updates on this? Joao, Have you tested with the patches suggested in #15? Thanks.
No, it doesn't boot with acpi_use_timer_override. I'll try the patches next.
Actually, it did on my board, but that was with a different version kernel. A BIOS UPDATE FIXED IT TO WORK WITHOUT ANY OVER-RIDE. (However I did enable the HPET timer in the bios that showed up after the update.) Check your board and make sure you've flashed the latest version of the bios (And then the one before that if it doesn't work but there is an earlier version that could work in case they screwed it up again...)
Any updates on this one ? Latest mainline 2.6.27-rc5 has lots of updates in that area, so any reports against that would be appreciated
Working with 2.6.27-rc5.
