Hi
We are experiencing a problem with one of our FreBSD 6.2 machines. The
machine has been running fine for months until we had to reboot it. Now
it doesn't boot anymore. After the boot loader we get what looks like a
register dump:
FreeBSD/i386 boot
Default: 0:ad(0,a)heap
boot: /boot/kernel/kernel\
int=000e err=0002 efl=00010086 eip=c042426a

BTX halted
and the machine reboots.
Any suggestions what might be the problem? All I can find about BTX
halted references to problems when installing a fresh system and not
out of a sudden on machine which has been running fine before.
Any hints are highly appreciated.
This is telling you that the boot loader has become corrupted, and
is crashing. A leading cause for this would be hardware failure --
something gone wonky with your hard drive.
Try booting the 'fixit' system from the installation media and see
if you can fsck and access the filesystems on the disk -- it may be
a localised problem that's killed the ability to boot from the drive leaving
the rest unaffected. Or the entire drive may be toast, and
you've got no option other than to get yourself a new drive and restore
from backup. Actually, given the fairly cheap price of disks nowadays,
I wouldn't try too hard to fix up the original disk: if you're going to
have to spend some hours working on it, it's more economic to ditch
the old one and start afresh.
Cheers,
Matthew
