Hi,
I'm having very frequent hangs on my SCSI bus, typically just when
cdrecord or cdrdao are in the initial phase of laser calibration.
I'm using Red Hat linux 6.2 (kernel 2.2.16-3) and a Smart&Friendly
CD-R 4012 cdwriter. The rlevant error messages are:
Nov 23 10:47:06 tandar35 modprobe: modprobe: Can't locate module char-major-97
Nov 23 10:47:15 tandar35 last message repeated 7 times

The reference to module char-major-97 (pg ATAPI through a parallel
port, I belive) is mistery to me. I have no such cdroms on my paralel
port, but a printer.
Any hints?
Thanks a lot in advance?
