Tried that and started

Kernel went in panic and automatic reboot in about an hour... <sigh>
It gets worse... when it does reboot the disk drive will not show in
the BIOS, nor does FreeBSD recognize it during boot. The system
actually has to be turned off to reset the drive...
This is bad...
Any other suggestions?
Sounds like a bug in the support for your ATA hardware, or your
hardware is broken. The very least you'll need to do is to obtain a
crashdump and debugging backtrace (see the developers handbook) and CC
it to sos@
This is getting funnier...
I added:
dumpdev="AUTO"
to: rc.conf
Rebooted the system and tried to get it to crash again...
And indeed it does in process 9: taskq
Then it starts dumping which takes a couple of seconds as the machine
has 2 GB Ram...
Than it reboots... and the next thing you know... savecore does NOT
recognize a dump on the swap file system. If does not save anything to
/var/crash... <sigh>
Tried this about 10 times... No luck...
Any other idea's?
Well... since capturing a kernel debug dump does not seem to be working
I had an other crash (is not that difficult to reproduce) and copied the
console screen with the information...
Here it is, for whatever this is worth...
