(To recap: I'm having ACPI problems on a DFI CD70-SC, with both 5.1-R and
5-CURRENT. Booting GENERIC doesn't show any problems, however, so there's a
good chance it's a misconfiguration issue.)
Thus spake Damian Gerow (damian@sentex.net) [15/09/03 17:34]:

Okay, here's a backtrace with debugging. Unfortunately, when dropped to the
debugging prompt, I don't know what to do. Attached is the kernel config I
used to generate this on 5.1-R, I can re-do this on -CURRENT if need be.
Here's a snippet of boot, and the stack backtrace:

Given that I caused a panic while in the debugger, and that I don't know
what I'm looking for, I stopped here. (Further 'show map's didn't result in
a panic, however.)
Note that if I /don't/ boot with ACPI, I can boot just fine, with no power
management.
