(I composed this message tfor the Redhat 5 Hurricane list but I think it
is relevant to the linux-scsi list.)
A while back I posted a problem with kerneld exiting as soon as it is
started. It just silently exits. Many suggested I did not have module
support in my kernel which I did. I had at the time a basic Redhat 5
installation.
Recent adventures with a CDROM writer has revealed an aspect of the
problem.
For background, my Intel based system has an Adaptec AHA-2940 SCSI adapter
which hosts by SCSI boot drive and a NEC CDR-1410 SCSI CDROM drive.
Recently I unplugged my NEC CDROM to play with a Yamaha CDR100 SCSI CDROM
drive. Somewhere along the way I realized that kerneld was now working! I
have since confirmed that whenever the NEC CDROm is installed in my system
kerneld will not work. It just silently exits.
What the heck is going on here!? BTW, Redhats position has been that since
the install worked I was not entitled to support on this problem. That's
seems like crap to me. A broken installation is an incomplete
installation.
Anyway, below is the output of dmesg. My kernel version is 2.0.31.
If anyone can help I will be most grateful. Please let me know if further
information is required.
