Description of Problem: EXP CRW-785 CD-RW station attached via PCMCIA fails to work in ide-scsi IDE ATAPIemulation mode at 7.2 cdrom base level and with all available rpms applied a/o 2/25/2002.. /etc/lilo.conf contains 'append="hdb=ide-scsi hdg=ide-scsi"' /etc/rc.d/rc.local contains 'modprobe imm' 'modprobe ide-scsi' /etc/modules.conf contains 'options ide-cd ignore='hdb hdg' ' and yet system attempts to attach drive as hdb ide drive. 1st drive (internal 365xd laptop TEAC 4x CD read-only) attaches as scd0 and works read-only. Have also attempted to only define hdg in 3 files above, hdb forks fine as non-scsi and hdg has same problem. cardmgr version is 3.1.24 on RH6.2 and cardmgr version 3.1.22 on RH7.2. Seems to be very much PCMCIA related as drive and cardmgr are not loaded or powered up into PCMCIA comes active. There are differences between the config files between 6.2 and 7.2. Have also noticed that when hdb is defined as SCSI, driver doesn't load until mounted.. FSTAB for hdg is defined automatically when PCMCIA comes to life as hdg (/dev/cdrom1 /mnt/cdrom1) attempt to mount results in "mount: /dev/cdrom1 is not a valid block device". On RH6.2 loads as exp cd940 "vendor:LG MODEL:CD-RW CED8080B . Notable on RH7.2 on reboot of system without power off error on restart "./config.opts line 8:no functional bindings" and on sytem shutdown cardmgr gets error 1 in cardmgr/pcmcia shutdown.. Also cdrecord -scanbus NEVER FINDS PCMCIA attached EXP CD-RW drive.. Have tried a complete reinstall of RH7.2 via CDROM, fails at base level and after apply of ALL available RPM's from RHN as of 2/25/2002. Version-Release number of selected component (if applicable): RedHat i386 7.2 base and RedHat i386 7.2 with ALL available RHN RPMS for system as of 2/25/2002. How Reproducible: Steps to Reproduce: 1. 2. 3. Actual Results: Expected Results: Should load and install as on RedHat 6.2 Additional Information: Will provide additional information on demand by e-mail Request.
I have applied the new kernel rpms for 2.4.9-31 and the problem still exists.
Found a workaround changed /etc/rc.d/rc.local from 'modprobe imm' 'modprobe ide-scsi' to 'modprobe imm' 'modprobe -r ide-scsi' 'modprobe ide-scsi' The system now picks up the 2nd cd-rom (CD-RW) drive and it works. cdrecord -scanbus finds Both the r/o and r/w cdrom drives (as SCSI) and X-CD-Roast configures and works. Still getting the other errors on reboot and shutdown sooo there is still some sort of a problem.
