Hello,
I am using an ultra 2 with two 300 MHz CPU's, kernel 2.6.18.5.
I tried to make a VOIP appliction (twinkle) work on my machine.
I have to use the OSS emulation layer, if I configure ALSA in
the application it will not work.
With OSS it works fine for a while, but after exactly 99999 IRQ's
from the cs4231 card I get the following kernel message:
irq 7: nobody cared (try booting with the "irqpoll" option)
Call Trace:
[000000000046df14] __do_IRQ+0xec/0x140

Disabling IRQ #7
After this, sound stops working.
Booting with the irqpoll option as suggested gives an endless
stream of errors as soon as I use sound. I get following repeated
message:
SYSIO[1f]: Uncorrectable ECC Error, primary error type[???]
SYSIO[1f]: DOFF[7] SIZE[7] MID[1f]
SYSIO[1f]: AFAR[000001ffffffffff]

SYSIO[1f]: size[2] MID[1]
SYSIO[1f]: AFAR[000001ffdc000010]
SYSIO[1f]: Secondary SBUS errors [(none)]
Any idea what the messages mean or what I can do to correct the problem?

Georg Chini
