PROBLEM: (82405) (PATCH ID: OSF425-1054)
********
This patch prevents a panic on TurboLaser systems with a DE600 in pci slot 0.
Mis-identification of the DE600 in pci slot 0 causes data structure
corruption.
This panic has been seen when starting up CPQ_MIBS, touching the corrupted
data structure.  The system panics with the following stack trace:

crash> tf
>  0 stop_secondary_cpu
   1 panic
   2 event_timeout
   3 xcpu_puts
   4 printf
   5 panic
   6 trap
   7 _XentMM
   8 strlen
   9 hal_getsysinfo
  10 getsysinfo
  11 syscall
  12 _Xsyscall

A message similar to the following may also be seen in the messages file
and the console:

Set IRQ-1758682592 to edge-trigger not supported
