I simply added 'device pcm' to the kernel config, when booting on new kernel I get lots of errors like this: ESS Technology Maestro-2E port 0x1400-0x14ff irq 5 at device 8.0 on pci0 ../../../vm/uma_core.c:1333: could sleep with pcm0 locked from ../../../dev/so und/pcm/sound.c:134 This is a well known problem; it's basically a diagnostic message telling you that there's a deficiency in the pcm driver. If you want to fix it permanently I suggest that you go and have a look at dev/sound/pcm/sound.c:134 and look for a way of invoking UMA without holding the lock. If you just want to work around it, you can probably disable INVARIANTS and WITNESS in your kernel configuration and hope that it won't turn into a real problem (ie. panic.)

Hello: Im a bit corious about what's the meaning of UMA. Thanks and sorry fot this simple question :) JFRH.

Thanks and sorry fot this simple question :) UMA is the Universal Memory Allocator, written by Jeff Roberson. It's the memory manager and things like malloc(9) make use of it. It was quite recently committed to -CURRENT so if you search the archives it shouldn't be too hard to find mails describing it in more detail.
