trouble generating a core file

[Chuck Tuffli <chuck_tuffli@xxxxxxxxxxx>]

I have a user who is being sadistic to my driver and ultimately causes a 
panic. Once ddb pops up, I tried typing 'panic' to generate a core file, 
but the system prints out the following:

LWKT_WAIT_IPIQ WARNING! 1 wait 0 (-1)
panic: LWKT_WAIT_IPIQ
mp_lock = 00000001; cpuid = 1; lapic.id = 01000000
boot() called on cpu #1

The (-1) number cycles through the values from -1 to -9 and then seems 
to hang without dumping a core. The kernel is based on the _Preview tag 
from today using a GENERIC conf file with DDB, SMP, and IOAPIC enabled. 
The system is based on an Intel chipset (SE7221BK1-E) and has a P4 with 
hyperthreading enabled.

The above message doesn't print out with HT disabled and it appears that 
the core is being written out. But, then the following is displayed at boot:

Checking for core dump...
savecore: reboot after panic: from debugger
savecore: system went down at Wed Dec 31 16:00:56 1969
dump time is unreasonable

When the system comes up, the date is

Sun Feb  5 22:40:48 PST 2006

Prior to the machine crashing, the date got set with 'rdate -n 
us.pool.ntp.org' and was correct, but the system has come up with that 
particular date from time to time today.

For now, I can live without HT enabled, but I'd like to get a core file. 
Is the proceedure I'm using to generate the core wrong? Also why is the 
system date so wacky? TIA!
