Hi,
tonight the box I use for the NetBSD mirror paniced with:
Panic: lockmgr: release of unlocked lock!
Begin traceback
  
lockmgr ( cf5d5f9c,6,d058d858,cf5d5f9c,10002)
layer_unlock+0x6b
layer_inactive+0x2d
vput+0x72
lookup+0x2af
namei+0x138
vn_open+0x60f
sys_open+0xcb
syscall_plain+0x17e

mrtg graphs don't show any unusual activity. It looks like it paniced while
doing rsync of the cvs tree (but it's the first time this happens
Since october, the date at which I installed a SMP kernel).
Any idea ? This is a 2.0_RC3 kernel in case it matters.
