I just tried (under FreeBSD 7.0-RC1) to mount an ext2fs volume - I've

the volume under the mount point, so the mount seemed to "work", but the
process is stuff. "ps" shows:
root 1307 0.0 0.0 3156 792 p6 D+ 5:21PM 0:00.00 mount
/mnt/linux-home
The "ps" man page says that "D" means: "Marks a process in disk (or
other short term, uninterruptible) wait."
Is there any way I can investigate what is going on? I cannot umount
(device busy) or break out of the mount command...

But unfortunately I do not have KDB and DDB compiled into the kernel.
And, obviously, if I reboot, I will lose this opportunity. I suspect
this to be an intermittent thing. Is there anything I can extract while
the system is running that would be useful?
Thanks, Joe
You can run kgdb on /dev/mem to obtain the backtrace.
