I tried to implement your ideas, I disabled sync, I don't know how you
disable disconnect/reconnect. Anyway, I don't think that's the problem.
The problem is the sigsegv in mount the oops causes, do we have something
like a 'half' mounted device?
Unable to handle kernel paging request at virtual address 00000000, epc ==

epc : 88021bcc

I get those other messages ...
scsi: aborting command due to timeout ...
... when I try to access the directory where I mounted the CDROM drive.
Do you think my SC hack is causing this mess?
