Description Klaus Wolf 2004-11-21 19:25:04 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux 2.6.9-1.678_FC3; X11; i686; en_US, de) (KHTML, like Gecko)

Description of problem:
After warm boot, CDROM/DVDROM is not recognized.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot FC3
2. reboot

Actual Results:  No /dev/hdb exists.

Expected Results:  /dev/hdb should exist.

Additional info:

Proper dmesg output:

Nov 18 21:11:58 golulu kernel: hdb: PIONEER DVD RW DVR-106D, ATAPI CD/DVD-ROM drive
Nov 18 21:12:00 golulu kernel: hdb: ATAPI 32X DVD-ROM DVD-R CD-R/RW drive, 2000kB Cache, UDMA(33)

Erroneous dmesg output:

Nov 18 19:53:36 golulu kernel: hdb: probing with STATUS(0x40) instead of ALTSTATUS(0x58)

Error never occured with vanilla 2.6.9 kernel. Windows has no problems detecting the device. FC3 detects properly after cold start (turning the computer off - just RESET doesn't work).

Problem appears to be BIOS/initialization related. Sorry for any
