When trying to make dumps using dump(8), the system still hangs,
if tagged command queueing is enabled.
Bad news is, that removing every AHC_xxx option doesn't result
in a stable system as well.
My machine sometimes hangs, but unfortunately doesn't panic.
All I can do is write down some of the error messages in the X
console.
sd0(ahc0:0:0) timed out while idle
LASTPHASE == 0x1, SCSISIGI == 0x0
SEQADDR == 0x10
ahc0: Issued channel A Bus Reset, 2 SCB's aborted
clearing bus reset
clearing 'in-reset' flag
ahc0:4:0 synchronous at 4.4 MHz offset == 0x8
spe_getpages: I/O read error
vmfault: pager input (probably hardware) error,...
BTW, this is an unmodified 2.2-GAMMA kernel of today.
