Subject2.5-bk oops in vsnprintf/scsi_mod
Hi,

got this one :(

bk pull from linux-20020923-211332 UTC

Linux megablast 2.5.38 #52 SMP Mon Sep 23 21:52:55 UTC 2002 i686 unknown
gcc version 3.2
binutils-2.13.90.0.4

could be related to sym53c416 module re-loading (after cli() removal; see
diff I posted some minutes ago). Seems the driver needs more cleanup ...
--- dmesg extract ---
scsi: device set offline - command error recover failed: host 0 channel 0 id 3 lun 0
Trying to free free IRQ5
scsi : 1 host left.
Unable to handle kernel paging request at virtual address da68a828
