It freezes kernel (sysrq do nothing) after lines:
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: TEAC Model: CD-W512EB Rev: 2
Type: CD-ROM ANSI SCSI revision: 02
scsi scan: host 0 channel 0 id 0 lun 0 identifier too long, length 60, max 50. \
Device might be improperly identified.

how ever after above message kernel causes hard hw lockup. IDE activity LED is turned on but nothing else works. (nor sysrq)
I believe that code that report this message causes hw lockup.
sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray
There are several different patches to ide-scsi in Linus's snapshots that will most likely appear in lk 2.5.55 . See:
http://www.kernel.org/pub/linux/kernel/v2.5/snapshots/
with patch-2.5.54-bk6 being the most recent. See the associated log for a listing of the ide-scsi changes.
It would be interesting to hear if that snapshot fixes your ide-scsi problem.
