Filed under CORE/pcm as per crimsun's suggestion in #alsa. I had this issue also with Gentoo 1.0.10-r1 but then I got an oops and a double exception that looked pretty nasty. After updating to 1.0.11rc2 I don't get the oops but still get the bug. The USB device is a self-made TI PCM2902 reference design. Sometimes I have to unplug/replug the device twice to tickle the bug, sometimes just once is enough. Kernel error message: ALSA /var/tmp/portage/alsa-driver-1.0.11_rc2/work/alsa-driver-1.0.11rc2/acore/timer.c:876: timer 0xf7fa4200 is busy? ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 01-10-06 09:25 stuge New Issue 01-10-06 09:25 stuge Distribution => Gentoo Linux 01-10-06 09:25 stuge Kernel Version => 2.6.15 ====================================================================== ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
