That's odd.
I've tried some kernels from my backups, and it seems that the
problem occured somewhere between nov. 12th and nov. 15th (see
below).
What additional details could help? I could boot with verbose
autoconfig, but I have to do it via serial console, since the output
is too large for the dmesg buffer.
Ciao,
Kili

Matthias Kilian [EMAIL PROTECTED] wrote: Hi, I just noticed that the cd and dvd drives connected to my Tekram DC-390 host adapter aren't detected since a few days. What follows are the dmesg of my current system and a diff against a dmesg some months ago. Please note that a) in my current system, Ottos patch to sys/sys/queue.h is applied, b) I roughly remember to used one of the drives a week ago. If this is neither a PEBKAC nor a known issue, I'll have a look at my recent backups and search for the very last time the drives have been detected.
