serious cd writer kernel bug 2.4.x

[James Stevenson]

Hi

basically i am having serious problems with a cd writer since i moved to
2.4.x it works fine under 2.2.x though this seems to happen on access to
the writer at any time have not even tried to write to it yet.

if a program trys to access the device i get the logs below followed
by an opps (no opps output yet my serial logged is messing up)

the devices are as follows the 44x drive works fine. the other one does
not.

hdc: HP CD-Writer+ 7200, ATAPI CD/DVD-ROM drive
hdd: IDE/ATAPI CD-ROM 44X, ATAPI CD/DVD-ROM drive

SCSI subsystem driver Revision: 1.00
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
  Vendor: HP        Model: CD-Writer+ 7200   Rev: 3.01
  Type:   CD-ROM                             ANSI SCSI revision: 02
  Vendor: ATAPI     Model: CD-ROM 44X        Rev: T4C2
  Type:   CD-ROM                             ANSI SCSI revision: 02
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
Attached scsi CD-ROM sr1 at scsi0, channel 0, id 1, lun 0

i will try to get the info on the opps but it most of it scolls off the
top of the screen. i have been able to reproduce this 100% so far
any help would be usefull.

thanks
