I'm having some problems with a CD-ROM drive being detected by FreeBSD at
boot-time. Quite often, when booting, the entire boot process hangs after
the atapi driver has printed "unknown phase" a couple of times. Sometimes
it boots successfully, and in those cases the CD-ROM is found to be:
wdc0: unit 1 (atapi): <CD-ROM Philips PCA408CDB/UH02>, removable, intr, dma, iordis
acd0: drive speed 6890KB/sec, 120KB cache
acd0: supported read types: CD-DA
acd0: Audio: play, 255 volume levels
acd0: Mechanism: ejectable tray
acd0: Medium: no/blank disc inside, unlocked
(the wcd0 line is always present.) On another machine, the boot process
doesn't even get as far as FreeBSD, the BIOS just gives a hard disk
failure message. Yes, this *does* suggest the CD drive is dodgy, but
since it sometimes works OK on the machine it was bought for, it would
seem all is not lost.
Any ideas on getting this drive to work a bit more reliably? (Short of
getting a replacement, I can just see it now: "well, since you're not
using Windows, your operating system must be faulty".)
