F.05 04/26/2007 ^^^^^^^^^^^^^^^ Hmm, I thought that this might be the case. Can you please try to boot -rc7 with kernel parameter acpi_skip_timer_override and send the same output (dmesg again also with apic=debug and lspci -nnxxxx) Thanks, Andreas PS: My assumption is that the patch in -rc7 leads to usage of IO-APIC pin2 for timer interrupt (potentially I have broken chipset revision determination for some SB600.)
