Aha... Actually, if you read the patch, you'll see why that's no
longer the case. I had in fact forgotten that I'd had to patch the
patch to make my VIA box boot (it was 6 months ago now!). I now do "if
(hwgroup) ..." in the test-for-busy section. So, the new patch does
NOT now cause panics on VIA.

Yes, only some chipsets end up in ide_config_drive_speed() at bootup;
notably the PIIX doesn't and the VIA does. Mea culpa! I should have
posted the fixed patch perhaps, but then it was deprecated and I
thought Andre had a better fix in hand. (BTW, when you say you had
"the same fix", you mean you fixed it independently or you used my
patch from May '02?)\x13

Well, do they have the trigger ingredients? You MUST have an IDE CDROM
sharing a bus with a HDD. Also, the perfect recipe for disk corruption
is to reboot, and then log in to your chosen desktop, and while it's
hammering the disk starting everything up, it should fire off
"magicdev", which in turn loads ide-cd: BOOM. RedHat 7.x with GNOME
does things in this order. YMMV.
