Description P. Beltrani 2001-02-07 01:00:58 UTC
System has a CD-ROM (master, /dev/hdc) and CD-RW (slave, /dev/hdd)

Attempts to mount a cd using using the CD-RW cause the system to lock-up.

The drive is a CenDyne CDICD00047 which I believe is a repackaged Ricoh RW7063A

  brw-rw----  1 root  disk  22,  64 Jan 18 01:16 /dev/hdd

Procedure to generate failure:

1) boot to run level 2

2) Login as root

3) from command line execute: mount /mnt/cdrom

This generates the following syslog entries

 kernel: hdc: ATAPI 50X CD-ROM drive, 128kB Cache, UDMA(33)
 kernel: Uniform CD-ROM driver Revision: 3.12
 kernel: hdd: set_drive_speed_status: status=0x51 { DriveReady SeekComplete
Error }
 kernel: hdd: set_drive_speed_status: error=0x04
 kernel: hdd: ATAPI 32X CD-ROM CD-R/RW drive, 2048kB Cache, DMA

4) Unmount and eject cdrom

5) from command line execute: mount /mnt/cdrom1

 At this point the CD spins up and the system locks-up

Misc info:
 1) The current hardware configuration works fine under RH 7.0.

 2) "eject /dev/hdd" will eject the tray WITHOUT locking up the system.
(Provided this is done before attempting to mount it)

 3) The system WILL boot correctly from a RH 7.0 CD in /dev/hdd

 4) The system will ATTEMPT to boot the RH fisher CD in /dev/hdd.  However
it locks up shortly after displaying the line "running /sbin/loader"
followed by a blue screen.

assigning to kernel.

Comment 2 Glen Foster 2001-02-08 16:00:40 UTC
We (Red Hat) should really try to resolve this before next release.

Comment 3 P. Beltrani 2001-02-27 15:17:30 UTC
Did a clean install of release 7.0.91, Wolverine. The problems appears to have
been resolved in this release.

Comment 4 David Lawrence 2001-02-28 03:10:16 UTC
Always nice to see bugs fixed.  :-)  Thanks for letting us know.

Comment 5 Glen Foster 2001-02-28 15:35:54 UTC
This is a test message, to see if we can reproduce a problem -- please ignore
