Red Hat Bugzilla – Bug 4902
PNP cdrom - can'd cold boot - hangs the system
Last modified: 2008-05-01 11:37:51 EDT
The cdrom prevents booting unless WIndows has been booted
and Red Hat boot is invoked without a power off.
When the system hangs on a cold boot the message on the
console refers to pc_cdrom is confused - lost interupt
reason 0x1. Values entered on Lilo have no effect on this
Boot's OK on windows.
We will need to know more about your hardware. For example brand/model
of the cd-rom that you are having trouble with. Is it an ATAPI IDE
drive or a proprietary drive?
I am using:
io magic 52x cdrom on ide 2nd slot as primary(not slave) /dev/hdc
It is ATAPI as far as I know
The 1st ide contains 2 drives 2.2GIG each - Western Digital
IWILL premium motherboard
64 MEG 60 ns EDO memory
One IBM 9.1 GIG SCSI drive.
This condition existed before I installed the SCSI Drive.
IF I BOOT WINDOWS, AND THEN REBOOT RED HAT WITHOUT POWER OFF THE
CD ROM WILL WORK. IT WILL NOT WORK FROM A COLD - POWER OFF BOOT.
Hope this helps. I want eventually to get rid of the windows OS
I have the same problem with RHL 6.1 and ATAPI/IDE CD-ROM as single (master)
unit on 2nd IDE controller. However, if I disable the recognition of the CD-ROM
drive at the AMI-BIOS setup level (but not the controller of course!), the
systems boot properly... Since I never succeeded booting an el-Torito CD-ROM
with this computer, I can imagine that this BIOS version does some dirty CD-ROM
initializations that DOS and WinNT reset, but not Linux... shame !
Is this still happening with the 2.2.16-22 kernel?
Closing due to lack of information.
