Same here; upgraded two news boxes from 4.1-STABLE to 4.1.1-RELEASE and they
were both crashing regularly. Here's three panics from the worst culprit:
*** #1 ***
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x14
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc012f69f
stack pointer = 0x10:0xc7d6ea18
frame pointer = 0x10:0xc7d6ea80
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 5 (syncer)
interrupt mask =
trap number = 12
panic: page fault
syncing disks... panic: lockmgr: locking against myself
*** #2 ***
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x14
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc012f69f
stack pointer = 0x10:0xc7d6ccc8
frame pointer = 0x10:0xc7d6cd30
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 4 (bufdaemon)
interrupt mask = bio
trap number = 12
panic: page fault
syncing disks... 397 397 397 397 397 397 397 397 397 397 397 397 397 397 397 397 397 397 397 397
giving up on 345 buffers
*** #3 ***
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x14
fault code = supervisor read, page not present^
instruction pointer = 0x8:0xc012f69f
stack pointer = 0x10:0xc7d6cc94
frame pointer = 0x10:0xc7d6ccfc
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 4 (bufdaemon)
interrupt mask = bio

Spot the pattern:
utserv% grep ^instr nakaleen
instruction pointer = 0x8:0xc012f69f
instruction pointer = 0x8:0xc012f69f
instruction pointer = 0x8:0xc012f69f
instruction pointer = 0x8:0xc012f69f
instruction pointer = 0x8:0xc012f69f
instruction pointer = 0x8:0xc012f6a3
The last one is running a debug kernel, but I didn't manage to either get a
dump or get into the debugger. :-(
nakaleen% nm /kernel.debug | grep ^c012f6a3
nakaleen% nm /kernel.debug | grep ^c012f6a
nakaleen% nm /kernel.debug | grep ^c012f6
nakaleen% nm /kernel.debug | grep ^c012f
c012f4b4 t ahc_action
I've reverted to 4.1-STABLE from around 7th August, which is fine, except for
the kvm change between the two. Bah.
