I just tried to boot my machine with a Jul 18th -current kernel.  I
have two scsi disks (sd0 and sd1).  It fscks sd0 fine, but fails to
fsck sd1.  It will set there for up to 30 minutes (I waited that
long one, 5 minutes longer than normal the other times (total 10)).
This is true over multiple attempts to boot the kerenl.  A Jul 12
-current kernel doesn't exibit this behavior.

The only delta between the two kernels (modulo source changes between
those dates) is that I upped max users from 10 to 20 so that my X
builds won't fail with can't for in imake.

My system is a 486DX2-66 with 32M of memory, a VLB bus with an
UltraStor 34F and a SMC8216C that has been running FreeBSD in this
configuration since about FreeBSD 1.1R (and 1.0GAMMA w/o the SMC card
or 16M of memory).

I know this is scant information.  How do I force FreeBSD to dump a
core file that I can use gdb to send a reasonable traceback for
further analysis.  I'll be trying again in a day or three with the
then current kernel.

Thanks for your help

Warner
