Hello!
In current -git kernels, when I modprobe a module which pulls in
additional modules, I get a few spurious interrupts, like so:
# modprobe snd-soc-exm32cexx
No device for DAI au1xpsc_i2s
No device for DAI au1xpsc_ac97

EXM32_CE05 Audio: using AC97
AC97 SoC Audio Codec 0.6
asoc: AC97 HiFi <-> au1xpsc_ac97 mapping ok
The hexvalues are c0_status, c0_cause, c0_epc, alchemy ic base and irq base.
ExcCode in c0_cause is 7 which according to the documents I read means
"Bus Error Exception (data reference)". The EPC points to various places
inside memcpy.S.
Curiously, if I remove "#define cpu_has_llsc 1" from
mach-au1000/cpu-feature-overrides.h
they disappear. The same board-code on 2.6.30 also is unaffected.
Before I start to bisect this I wanted to ask if someone in here might
have an idea as to what could be responsible?
Thanks!
