8.0-RC2 on Rackmac3,1 - fatal kernel trap

[Carlo Dapor]

Hmm, bad news.
The 20091112 ISO was used, if that matters.
No extra configuration was taken, just hit the enter key when prompted so.

The kernel does not correctly handle acd0.

Here's the relevant log

....
acd0: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout -
complete request directly
acd0: TIMEOUT - READ_BIG retrying (1 retry left)
acd0: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout -
complete request directly
acd0: TIMEOUT - READ_BIG retrying (0 retries left)
acd0: FAILURE - READ_BIG timed out

This is repeated over and over.
Finally this:

panic: mtx_lock() of destroyed mutex @ /usr/src/sys/kern/kern_sema.c:79
KDB: enter: panic
[thread pid 12 tid 100016 ]
Stopped at 0x333d88:    addi   r0, r0, 0x0

The computer was very loud.

I entered continue at the prompt, and a reboot resulted.
