yes, i have already recompiled my kernel with sysrq support, also in order
to get some more debugging information in case the 'lock-up of death'
should strike again.

it's interesting you're also using a cd changer... i have 24 cd's on 4
nakamichi mbr-7 changers always mounted, probably some sort of an "extreme
situation"

actually, before the last lock-up tonight i had some scsi timeout errors in
my logs:

Jan 26 20:30:58 mir kernel: scsi : aborting command due to timeout : pid

i have to admit, i used to have those timeout problems under 2.0.x as well
every month or so, there might be a problem with my aha-2920 or one of the
cd changers, but that has never caused a hard lock-up on any kernel before
pre8
since i don't have any scsi disks, i load scsi support as a module (like
almost everything else i could modularize):

my scsi .config:

CONFIG_SCSI=y
# CONFIG_BLK_DEV_SD is not set
# CONFIG_CHR_DEV_ST is not set
CONFIG_BLK_DEV_SR=m
# CONFIG_BLK_DEV_SR_VENDOR is not set
CONFIG_CHR_DEV_SG=m
CONFIG_SCSI_MULTI_LUN=y
# CONFIG_SCSI_CONSTANTS is not set
# CONFIG_SCSI_LOGGING is not set
CONFIG_SCSI_FUTURE_DOMAIN=m

lsmod:

nls_iso8859-1 2020 24 (autoclean)
fdomain 12332 24 (autoclean)
sr_mod 16284 24 (autoclean)
cdrom 12600 0 (autoclean) [sr_mod]
isofs 17464 24 (autoclean)

output of /proc/scsi/scsi (you asked for it ;):
