Binary package hint: linux-source-2.6.22

This is related to bug #141646 "Gutsy LiveCD won't start on Vaio SRX51 & SRX41" in that there is no way to start or install Gutsy without significant user intervention on Sony Vaio PCG-SRX51 or PCG-SRX41.

They boot from an external IEEE-1394 DVD-ROM/CD-RW drive.

Text installer fails with:

[Detect and mount CD-ROM]
Your installation CD-ROM couldn't be mounted. This probably means
that the CD-ROM was not in the drive. If so you can insert it and try again.

This despite the fact the CD has just booted!

This is a definite regression; Feisty booted and installed perfectly on these Vaios, and Gutsy LiveCD booted but failed due to other problems.

Dropping to the BusyBox I find the following devices listed:

scd0
sda, sda1-sda6
sdb
sg0 (sda - Toshiba MK3018GA hard disk)
sg1 (IEEE1394 CD-RW/DVD-ROM)
sg2 (sdb - MSC-U03 MemoryStick)

lsmod shows ieee1394, ohci139, sg, sbp2, scsi_mod loaded.

/sys/bus/scsi/devices/3:0:0:0 shows the files
block:sr0
ieeee1394_id
model ("CD-RW CRX820E")
state ("running")
scsi_generic:sg1

There is no /dev/cdrom

$ mount /dev/scd0 /cdrom

works and I can access the file system. After typing "exit" to return to the menu the CD is found and the next stage in the installer runs correctly and files are copied from the CD.
