This wil go some distance to explain a few lockups I've been having
recently.  Unfortunately, I don't know what half of this means, to me it
looks like interrupt problems.  My dmesg output has some more of these
(attached).  config also attached.  Lockups always occur during or after
intensive IO.

According to /proc/interrupts IRQ7 is not used:
           CPU0
  0:   75470904          XT-PIC  timer
  1:        160          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  4:         58          XT-PIC  serial
  8:          2          XT-PIC  rtc
 11:    1590851          XT-PIC  eth0
 14:     198818          XT-PIC  ide0
 15:     486218          XT-PIC  ide1
NMI:          0
LOC:          0
ERR:          3

And my logs.
