trouble generating a core file
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)
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
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!
