optical drives don't show up unless boot with media - then they disappear
I have two optical drives (not SATA) that previously showed up as /dev/hda and /dev/hdb. No longer. I see no mention of them in fstab and catting all the /dev/dvd /dev/cd... /dev/sr.. turns up nothing.
If I place a disk with info in the drive nothing appears anywhere I can see (not in dmesg). K3b tells me no devices found. wodim tells me Detected CD-R drive: /dev/sr1 wodim: Cannot do inquiry for CD/DVD-Recorder. Errno: 5 (Input/output error), test unit ready scsi sendcmd: fatal error CDB: 00 00 00 00 00 00 cmd finished after 0.000s timeout 40s (These are not SATA drives.) I noticed rebooting will show drives if there is media in there. However, that disappears after a while as well. Then inserting and reinserting cdroms gives no messages in dmesg. |
By disabling hal, the CDs seem to not disappear.
Code:
hal-disable-polling --device /dev/sr1 I had seen add noapic to the boot line in grub. That didn't help. |
I recompiled with a newer kernel (2.6.35.4) and a clean .cfg from another install and things work fine now.
