HiWe 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=0000000e err=00000002 efl=00010086 eip=c042426a eax=c06da7a8 ebx=c06da7a0 ecx=00000000 edx=f000ff53 esi=00000000 edi=c06da57f ebp=c08f6d4c esp=c08f6d40 cs=0008 ds=0010 es=0010 fs=0010 gs=0010 ss=0010 cs:eip=89 42 0c eb 07 90 8d 43-08 89 46 14 89 5e 10 8d 46 10 89 43 0c 8b 47 0c-89 43 10 85 c0 74 0b 8b ss:esp=7f a5 6d c0 00 00 8f 00-00 e0 8f 00 64 6d 8f c0 75 3b 42 c0 a0 a7 6d c0-7f a5 6d c0 20 a5 6d c0 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 -- Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate Kent, CT11 9PW
