Machine is an intel mac mini core solo.  Will get lspci momentarily.

Hrm, I'm away from my desk this week, what information do you need?  I'll have
somebody fire it up and look at it.

you mentioned lspci :)

Well yeah, but i wasn't sure that was actually needed.  I'll try to get somebody
to do that.

Well, kernel 2.6.20-1.3094.fc7 has no such problems, it sees the hard disk in
this very same mini without a problem.

spooky.   must have been a side-effect of the recent ATA hpa fixes. (though this
device doesn't have a HPA).

We still have problems once we try to boot this kernel (3094) off the installed
system. The installer has no issues, but the initrd falls over, the last few
messages being about not finding any logical volumes and failing to mount
/dev/root. Seems we've made mkinitrd unhappy somehow...

Got it booting. Seems to be a timing issue. Inserting a 10-second delay into the
initrd managed to do the trick -- scsi_wait_scan alone isn't cutting it here. :(

Weren't you installing and booting off of this box today?

Yeah, thought I closed this bug, whoops.
