Hello,

I synced the sources today to #196643.
And built a kernel with WITNESS etc. off.

My boot partition sits on zfs.

I get the below panic. Unfortunately I can't bt since the usb keyboard 
ist not functional at this moment.

---
Trying to mount root from zfs:zroot
spin lock 0x80dccc00 (sched lock 1) held by 0x8595baf0 (tid 100003) too long
panic: spin lock held too long
cpuid = 0
KDB: enter: panic
[thread pid 1 tid 100002 ]
Stopped at	kdb_enter+0x3a: movl	$0,kdb_why
---

Unfortunately I can't say exactly which version the previous, working, 
kernel has. The svn nbr has gone. (I have this subversion:
subversion-freebsd-1.6.5)

Here the top of the dmesg:

I start now with a WITNESS build.

Btw, on which irc channel, (bsdcode, bsddev) could such an issue be 
discussed?

Thanks for any hint on how to track this down.

Andreas
