FreeBSD 8.1-RELEASE-p1 #11 i386 DomU fault in kernel at _mtx_lock_sleep()

[Yuriy Kohut]

The issue is 100% reproducible. Just got it ones more:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address	= 0x8d78d0c
fault code		= supervisor read, page not present
instruction pointer	= 0x21:0xc00cbe2f
stack pointer	        = 0x29:0xe553f9e0
frame pointer	        = 0x29:0xe553f9f8
code segment		= base 0x0, limit 0xf9800, type 0x1b
			= DPL 1, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 7297 (sendmail)
[thread pid 7297 tid 100067 ]
Stopped at      _mtx_lock_sleep+0x3f:   movl    0x1a4(%ecx),%eax
