That's really interesting. I tried latest git (2.6.16-rc5) to see if this is still there. First of all, 32-bit is fine, both regarding i8042 as well as ALSA with a PCI audio card. With a 64-bit kernel, i8042 appears to be okay now. I get: Cobalt LCD Driver v2.10 i8042.c: i8042 controller self test timeout. Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled and the kernel boots fine. I then built ALSA support into the kernel to see whether http://www.linux-mips.org/archives/linux-mips/2006-01/msg00325.html disappeared too. I got almost the same oops as the one I got before because of i8042. Peter, does that make any sense to you? I assume your recent PCI fix may be related. ...
