[1.] - Kernel panic when I mount cdrom (linux 2.4.20-rc2).
[2.] - I make kernel with opt.
SCSI Support --->
<M> SCSI Support
<M> SCSI CD-ROM Support
(2) Maximum number of CDROM devices that can be loaded as modules
<M> SCSI generic support
ATA/IDE/MFM/RLL support --->
<*> ATA/IDE/MFM/RLL support
IDE, ATA and ATAPI Block devices --->
<M> Include IDE/ATAPI CDROM support
<M> SCSI emulation support
In lilo.conf I wrote append="hdd=ide-scsi"
In /etc/fstab
/dev/scd0 /mnt/cdrom iso9660 noauto, owner, ro 00
And when I try to mount cdrom system crash.
