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:

Is there some fix available?
