The original panic in kern/52718 is no longer reproduceable for me at
this time. After Jeff's latest changes, the panic moved from boot time to
panicking when I did an init 6. I could _not_ reproduce the new panic
if I built a kernel with DDB, but a DDBless kernel would panic every time
after init 6. Needles to say, that makes things really tough to track
After shit-canning the acpi module, it doesn't panic at all. I'm sure
the race conditions are still lying in wait, but due to a lack of
interest and the incredulous attitude of most on the mailing list, I'm
going to forget about it for the time being.
ACPI has always worked fine on my system, and I'm probably masking
problems by not loading the module. Since I'm running a desktop
system here, acpi doesn't really buy me anything, so apm is back in my
