Description

Hi,

I just got an LWKT_WAIT_IPIQ panic on a box running head from this
morning (UK time). hand copied trace

LWKT_WAIT_IPIQ WARNING! 0 wait 0 (-1)
panic: LWKT)WAIT_IPIQ
cpuid = 0
Trace beginning at frame 0xd6696cb0
panic (ffffffff) at panic + 0x164
panic (c040bf26, deadc0de, c67096a0, ff000000)
lwkt_wait_ipiq (deadc0de, 1, deadc0de, c01e5c34, c67096a0) at

callout_stop (c670960a) at callout_stop + 0xe3
callout_reset (...)
filt_timer_expire (...)

lwkt_exit()

The box is running a vinum RAID0 on a couple of terabyte drives with
a Hammer filesystem on the mirror, an SSD for the OS and swap (16GB with
swapcache enabled) and three vkernel environments running various services
(incoming mail + dovecot, IPV6 tunnel termination with pf firewall, thttpd
web server) as well as NFS exports and mediatomb running on the host. It's
an Asus M4A78L-M motherboard with an AMD Phenom II X4 955 and 4GB of memory

I'm getting these at random intervals usually at least once a day.
I'm also seeing ssh stalls on ipv6 connections to the box (but not on ipv4)
and a boot time message:

clist_alloc_cblocks: M_NOWAIT kmalloc failed, trying M_WAITOK

I've no idea whether or not these things are related but they all
started about the same time:

Hi,

With an update to  v2.9.1.845.gc7506-DEVELOPMENT these panics have
become quite frequent (several times a day).
I finally got a dump out of one of the crashes - it's packed up at
http://www.sohara.org/crash.tgz
For the time being I'm running the box with a UP kernel in the hope
that it will be stable.

Hi,

With a UP kernel I'm getting this message at about the rate the SMP
kernel was panicking.
thr_umtx_wait: FAULT VALUE CHANGE 7366 -> 7367 oncond 0x284e0074
