Bug#258082: kernel: Failure to read partition table with advansys scsi
Package: kernel
Severity: normal
Stock debian kernel images 2.4.26 and 2.6 up to and including 2.6.5
work fine, happily read partition table containing root fs on SCSI disk.
Kernel images 2.6.6-1-k7 and 2.6.7-1-k7 fail to read partition table from disk,
though do seem to detect controller and disk. Unsurprisingly, eventual
kernel panic when root fails to mount.
"/dev/scsi/host0/bus0/target0/lun0: unknown partition table"
Not much more to go on than that...
Maybe related (same symptoms, similar hardware... different kernel tree):

There are a few changes between debian's kernel-source 2.6.5 advansys.c and
2.6.6+ advansys.c, though I haven't managed to prove those changes are
responsible, >2.6.5 is working fine on other boxes, so I believe
it to be advansys-specific.
Report might be more appropriate to LKML or linux-scsi, but since I'm using
debian's kernel, reported here first for referral at maintainer's discretion.
