Hello,
The panic happens when probing the various devices of the machine (dual
Celeron + 440BX), running the GENERIC -current kernel (with all debugging
options) :
panic: _mtx_lock_sleep: recursed on non-recursive mutex pcm0

the card is a :
none1@pci0:17:0: class=0x040100 card=0x4c4c4942 chip=0x50001274
rev=0x00 hdr=0x00
vendor = 'Creative (Was: Ensoniq)'
device = 'ES1373 AudioPCI'
class = multimedia
subclass = audio
the kernel and world sources were updated this morning around Fri Jun 1 06:48
UTC 2007. The kernel and world have been rebuilt via :
make update && make -DNO_CLEAN buildworld && make -j2 buildkernel
the source code for the specific board seems to be quite old :
FreeBSD: src/sys/dev/sound/pci/es137x.c,v 1.65 2007/04/18 18:26:39 ariff Exp
the previous kernel+world worked fine, including probing both sound cards (one
on PCI, and the other on ISA).
The same kernel is currently running after unloading all kld modules.
