Comment 25 for bug 96084

I believe I have a similar problem, but I fail to notice the modprobe abnormal exit, or it doesn't happen in my case. There are other things as well:
1. The 7.04 LiveCD boots only from my CD drive (IDE Slave) but not on my DVD drive (IDE Master) (April 4th image). This happens always. Whenever I boot from my CD drive it tries the floppy a number of times and then boots ok, but when I try to boot from the DVD drive it tries the floppy a whole lot more and then fails with the well known error message.
2. If I wait a bit I get the following error messages:
[ 60.101981] ata2.01: failed to set xfermode (err_mask=0x4)
[ 95.974137] ata2.01: failed to set xfermode (err_mask=0x4)
[ 131.706301] ata2.01: failed to set xfermode (err_mask=0x4)
[ 136.705051] ata2.00: failed to set xfermode (err_mask=0x40)
3. Looking through the init and casper scripts I understand they are looking for a loop device in /sys/block, but the only items I have there are:
ram0 - ram15 fd0 sda sr0
sda - my hard drive, sr0 - my dvd drive, my cd drive is not there (though not needed when the LiveCD is in the DVD drive)
4. comparing the output of udevinfo from my HDD and DVD drives, the DVD seems to be missing information: The E: ID_SERIAL is empty and E: ID_SERIAL_SHORT contains unreadable characters, while they are both ok for my HDD
