Default udev cdrom device issue

Hi all and thanks for reading

Recently my slack 10 box has been giving me issues. Mainly this is related
to what i think is a udev problem. You see i have 2 cd drives a reader and
a writer. They used to be hda and hdb. But for the last couple days the
device nodes /dev/hda and /dev/hdb have been missing from /dev.

"dmesg | grep CD" responds with

hda: SONY CD-ROM CDU5221, ATAPI CD/DVD-ROM drive
hdb: YAMAHA CRW-F1E, ATAPI CD/DVD-ROM drive

so the kernel sees them during the boot process, but they dont end up in
/dev. i am using a custom 2.6.7 kernel, which is based on the one shipped
with slack 10, just with unecessary drivers removed. I have been looking
around the net for a solution with no luck. If anyone has had this problem
before i and/or has a possilbe solution i would greatly appreciate any and
all feedback.

Thanks for your time

I presume this problem began with the kernel upgrade.

I had a different problem with udev when I upgraded to kernel 2.6.9
(which did not occur with 2.6.7). /dev/tty became a directory. The
thing I noticed was man pages suddenly wouldn't work. This was fixed by
upgrading udev to udev-035-i486-1. I see Slackware-current now has
udev-042 available.

If you suspect udev, I suggest you go ahead and upgrade it.

Hi!

I have the exact same problem with both the slackware 2.6.7 kernel and a
custom 2.6.9 kernel. My cd/dvd-player does not appear in /dev/ as hdc (as
it should).

I upgraded udev to udev-042 but I still cant find hdc in /dev
