NTOS: ... message in /var/log/messages && PANIC

Wed May 14 09:32:35 UTC 2014

Hello,

I have encountered on a system:

$ uname -a
FreeBSD La-Habana 10.0-CURRENT FreeBSD 10.0-CURRENT #0 r250588M: Sat Jun 22 14:15:48 CEST 2013     guru at La-Habana:/usr/obj/usr/home/guru/head/src/sys/GENERIC  i386

twice a PANIC, last line in /var/log/messages was always:

May  9 13:55:26 La-Habana kernel: NTOS: timer 0xc5ea5430 fired even though it was canceled
May 14 09:43:08 La-Habana kernel: NTOS: timer 0xc5f05430 fired even though it was canceled

What does this line mean?
Thanks

	matthias
