hi, running -CURRENT from a few days ago. my problem: I never get verbose boot messages complete from start to end, because the output of that super-duper pcm0 driver overflows the buffer: from 1491 lines in dmesg(8), 979 are like: 'dmesg -a': (this is where dmesg output starts(!), with the beginning missing) controller> mem 0xf7005000-0xf7005fff irq 21 at device 2.0 on pci0 ... pci1: <serial bus, FireWire> at device 14.0 (no driver attached) pcm0: <NVidia MCP61 High Definition Audio Controller> mem 0xf7000000- 0xf7003fff irq 23 at device 5.0 on pci0 pcm0: DMA Coherency: Uncacheable / vendor=0x10de pcm0: Reserved 0x4000 bytes for rid 0x10 type 3 at 0xf7000000 ioapic0: routing intpin 23 (PCI IRQ 23) to vector 52 pcm0: [MPSAFE] pcm0: [ITHREAD] pcm0: hdac_dma_alloc: size=1024 -> roundsz=1024 pcm0: hdac_dma_alloc: size=2048 -> roundsz=2048 ... pcm0: HDA_DEBUG: HDA Config: on=0x00000000 off=0x00000000 (971 more lines about pcm0 cruft deleted) how can i get rid of all that excess pcm0 info? I already tried to set: ``hw.snd.verbose="0"'', ``kern.consmsgbuf_size="16384"'' in boot/loader.conf, but it doesn't help. pcm(4) doesn't mention any more verboseness settings, neither does loader.conf(5). somebody got an idea? -c
