I don't know enough about this problem to create a bugzilla report yet.
I didn't notice any problems with my Toshiba scsi DVD-ROM SD-M1401 until
upgrading to 2.6.15.1 from 2.6.13.4. (this system, a Tyan Thunder
K7X-Pro (S2469UNG) dual 2400mp, has been stable since 2.4.18). Now,
most cd/dvd's I try cause a long listing of scsi errors in syslog. It
could be that the drive is going bad, but the system no longer
gracefully recovers from scsi errors. The other scsi drive, a YAMAHA
CRW2100S cd-rw does not generate any read errors on all the cd's I have
tried. Both 2.6.15.1 and 2.6.16.12 are causing system lockups. I
have rebooted back into 2.6.13.4 and my system behaves normally, ie, CD
read errors are simply reported to the shell, and processing continues.
In 2.6.15.1 I started to seeing these:
