Since a couple of releases ago my box fails to reboot, spitting out
scsi related errors and a kernel panic instead. At first I tought
this to be the double driver registration issue, but since the
latest kernel still has this problem...
This is 2.5.46 smp on a box with 2 scsi drivers like so:
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SCSI_AHA152X=y
CONFIG_SCSI_AIC7XXX=y
CONFIG_AIC7XXX_CMDS_PER_DEVICE=8
CONFIG_AIC7XXX_RESET_DELAY_MS=5000
The messages look like this (scsi0 is the aic7xxx):
Rebooting.
