Hello, after loading 'sound.ko' and 'snd_ich.ko' in my i386 notebook with 5.4-RELEASE, GENERIC kernel and the following modules: # kldstat Id Refs Address Size Name 1 15 0xc0400000 5dde24 kernel 2 1 0xc09de000 47e4 if_tap.ko 3 1 0xc09e3000 d164 kqemu.ko 4 14 0xc09f1000 56270 acpi.ko 5 1 0xc2784000 1c000 ipl.ko 6 1 0xc2867000 17000 linux.ko 7 2 0xc2ad2000 18000 sound.ko 9 1 0xc2b49000 17000 radeon.ko 10 1 0xc2af1000 5000 snd_ich.ko I detected that the box was running very slow and with high percentage of interrupts; this is aparently caused by the 'snd_ich.ko' somehow because during unload it says: # kldunload snd_ich Interrupt storm detected on "irq11: cbb1 pcm0+++"; throttling interrupt source pcm0: detached # kldload snd_ich pcm0: <SiS 7012> port 0x1800-0x187f,0x1c00-0x1cff irq 11 at device 2.7 on pci0 pcm0: <Cirrus Logic CS4299 AC97 Codec> After 'kldunload snd_ich' and 'kldload snd_ich' sound works a while but the Interrupt storm comes back after some time. This problem looks similar to: http://www.freebsd.org/cgi/query-pr.cgi?pr=80114 Is there some fix available?
