:The symptoms:
:- there were kernel panics, complaining about a page fault
:- I saw a message: "clist_alloc_cblocks: M_NOWAIT malloc failed, trying :M_WAITOK"
:- also saw this one: '[diagnostic] cache_lock: blocked on 0x3... "usr"'
: '[diagnostic] cache_lock: unblocked usr'
:The version I used is the 1.4 slip, cvsupped around 7th January afternoon.

   Well, you can ignore the clist_alloc and cache_lock diagnostics, those
   are harmless.

   The kernel panic is another matter.  We'd definitely need more
   information to figure out what is going on there, such as a kernel
   core and backtrace.

   I would never suggest that someone do a blind update of an inaccessible
   production server.  Sometimes things break!  Too late for you, I know,
   but there isn't much I can do to help without more information.  I can
   only suggest that the machine be reverted until you are able to test on
   a more accessible box.

I made a try with 1.5 cvsupped a few hours ago. It seems OK so far. The reason to upgrade was that I intend to use nullfs functionality for some jail configs. Sorry to say, I'm not going to be able to test this issue within a few months, becuse I have only one 4way box at the moment.

Best regards,
