(I hope this doesn't appear twice, the first time bounced because
my subscription lapsed when the mailing list host switched to sourceforge)
kernel 2.4.21-rc7-ac1
alsa 9.4 (drivers, utils, libs)
Tyan dual athlon MP S2460 motherboard
(I tried it once with numcpus=1 just in case its an SMP
problem, no change)
My SBLive! is the default soundcard.
imic is defined in .asoundrc as:
pcm.imic {
type hw
card 1
}
ctl.imic {
type hw
card 1
}
I get a hard lockup (need to cycle power) when I try either:
arecord -v -D imic --rate 44100 -f S16_LE - | aplay -v -
or
arecord -v --rate 44100 -f S16_LE - | aplay -D imic -v -
and then ^C to stop. Note, it runs fine until I ^C.
Running imic->imic or sblive->sblive works fine, ^C and rerun,
no problem. I've been using the SBLive! for years. I just
purchased the iMic.
It does print the "Aborted by signal Interrupt..." message
from alsa-lib twice (for arecord and aplay)
No log messages, oopses or other screen messages -- just locks up.
I have the driver configured --with-debug=full.
How may I help debug this further?
I'm able to reproduce safely now (the first time it happened
I got some filesystems corruption).
Just FYI here is the script I use to bring the system into a safe
state to crash ;-)
(I was unable to get the system to recognize the iMic when booting
in single user mode so I to bring it all the way up and then
down into single user mode. Any tips on this would be appreciated too,
I modprobed all the relevent modules and mounted usbdevfs, is there
something else?)
