| |
Motherboard: ASUS P55T2P4 motherboard (Intel 430HX chipset) CPU: AMD K6-III 400MHz CD-ROM: No-name ATAPI CD-ROM installed as master on IDE channel 1 (hard drive is attached as master on IDE channel 0) Kernel: Official 2.4.17 and Red Hat 2.4.9-21
Whenever I try to access the CD-ROM after boot, I get the following Oops:

After the Oops, lsmod shows:
ide-cd 27072 3 (initializing)
and the module is stuck at initializing. This CD-ROM worked fine on 2.2.20 as long as I booted with "hdc=noprobe hdc=cdrom" (otherwise I'd get "lost interrupt" messages). I have tried "ide=nodma" with no effect, as well as trying with the "hdc=" options both on and off. Running "hdparm -d0 /dev/hdc" before trying the mount causes the same Oops.
Any ideas?
