Initially quoting me, Bruce Evans said: >>... changing the contents of /etc/fstab (from wd1 based contents provided >>by the CD install to wd0 based contents) prevents the panic. >The kernel shouldn't be paniced by anything in fstab. It isn't even >used until after the root file system has been used to start init. While you didn't give me the actual answer to the problem, thank you for forcing me to investigate a different line to answer your comments. The essence of the actual problem can be seen by comparing the device probes with CD wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 1 (wd1): <IBM-DMCA-21440> wd1: 1378MB (2822400 sectors), 2800 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 0 (atapi): <TOSHIBA CD-ROM XM-1402B/15967, removable, intr, iordis wcd0: 1033Kb/sec, 128Kb cache, audio play, 255 volume levels, ejectable tray to the device probes without the CD wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <IBM-DMCA-21440> wd0: 1378MB (2822400 sectors), 2800 cyls, 16 heads, 63 S/T, 512 B/S I was trying to solve my problem the hard way. I was accepting the disk device name change and looking for a way to cope with it. One of the many times I inserted and removed the CD drive this evening, I noticed a tiny slide switch on the back, labeled with an "S" on one side and with an unreadable smudge on the other. It was set to smudge. After switching it to "S," the device probe turned into wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <IBM-DMCA-21440> wd0: 1378MB (2822400 sectors), 2800 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (atapi): <TOSHIBA CD-ROM XM-1402B/15967, removable, intr, iordis wcd0: 1033Kb/sec, 128Kb cache, audio play, 255 volume levels, ejectable tray Problem solved. Thank you for inspiring me. Sometimes all one needs is to talk (or type) about it. -- David E.
