Subject:   kernel hangs during boot
Message-ID:  <20031204165637.H76565@volatile.chemikals.org>

Just tried to boot a new kernel on my laptop since the ACPI code was
modular and OHCI was finally fixed, and instead of booting it hangs
right after (or during?) the ATA probe:

ata0-master: pio=0x0c wdma=0x22 udma=0x45 cable=80pin
ata0-master: setting PIO4 on AcerLabs Aladdin chip

acpi_cmbat1: battery initialization failed, giving up
panic: from debugger
Stack backtrace:


ACPI as a module doesn't seem to be the culprit, nor does atapicam or even
atapicd. Pulling out the dvd drive still hangs. My working kernel is from
Nov 18, so I'm at a loss to exactly when this problem showed up.
