Full dmesg (from a working kernel built from Jan 9th sources) and
kernel config attached.
Note that:
1) the problem disappears if I remove the pcm driver from the kernel
(yet I don't think it's directly at fault since the panic happens
when the ess driver is about to be initialized)
2) the problem also disappears if I enable KTR (see commented-out
entries in config file)
3) a fresh kernel without pcm boots but exhibits the same symptoms
kris reported, i.e. programs segfaulting for no apparent reason;
if / when they produce a core file, it is corrupted and useless
for debugging. I suspect a problem in the I/O system, possibly
similar to the one tegge discovered and fixed last week.
