Hi,

I'm trying to build a Hyper-V aware kernel/system from the SVN source at 
svn://svn.freebsd.org/base/projects/hyperv (r254955)

I got the world compiled, and the new Hyper-V supporting kernel installed, 
went to boot to single user mode, and get the following panic:

"
Timecounter "Hyper-V" frequency 10000000 Hz quality 10000000
panic: acquiring blockable sleep lock with spinlock or critical section 
held (sleep mutex) 4 Bucket " /usr/src/sys/vm/uma-dbg.c:212
cpuid = 0
KDB: enter: panic
[ thread pid 0 tid 100000 ]
Stopped at     kdb_enter+0x3e: movq    $0, kdb_why
db>
"

This is under Hyper-V 2012.

Any pointers? Is this a known issue?


Thanks,

-Karl
