Bug Description
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, PCG-SRX41 or Acer Travelmate C104CTi (and additionally any PC using an external IEEE1394 CD/DVD drive).
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/
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.
I managed to save the install logs to the local hard disk, boot into Feisty and transfer them over the network to my primary laptop.
I'm attaching syslog (81.5KB) to this comment, but the important bit would appear to be:
cdrom-detect: Searching for Ubuntu installation media...
cdrom-detect: CD-ROM mount failed: device=/dev/sdb
cdrom-detect: CDROM-detect failed; unmounting CD just to be sure
main-menu[3246]: (process:4299): mount:

main-menu[3246]: WARNING **: Configuring 'cdrom-detect' failed with error code 1
main-menu[3246]: WARNING **: Menu item 'cdrom-detect' failed.
Which appears to suggest cdrom-detect is not fully exploring the devices and assumes the MemoryStick slot is the CD-ROM device.
