It was very painfull for me and I don't get result...

#define UMA_DEBUG 1
#define UMA_DEBUG_ALLOC_1 1

in uma_core.c kill my machine.
I get tons of crap to serial console.
Server unaccessable over network too.
I ask colocation support for manualy reboot server, for access to
console and boot with old kernel.

Now I update world and kernel to RELENG_6 11/15/2006 00:00:00 UTC

Any other idea?

PS. unionfs switch off now. UMA debug switch off too.
