Hi!
I have had this kind of reboot about 5 times in the last couple of days:
Mar 8 16:26:14 yt savecore: reboot after panic: panic: kernel diagnostic
assertion "l->l_nopreempt == 0" failed: file
"/archive/foreign/src/sys/sys/userret.h", line 116 WARNING: SPL NOT LOWERED ON
SYSCALL 16384 24 EXIT ef20f930 6 WARNING: SPL NOT LOWERED ON TRAP EXIT 6 0
For some of them, I even have crash dumps:

I upgraded from a Jan 28 kernel to a March 3 kernel, and I think it
only started afterwards.
Any ideas?
