Hi, I was able to find another trigger for this sound glitch:
dd if=/dev/zero of=/tmp/test bs=1m count=256 rm /tmp/test Sound sometimes interrupts in the middle of dd(1) call, and always interrupts at the time of rm(1) call on files larger than 200 Mb. It looks like in case of dd/rm not only sound is affected, but mouse cursor controlled by USB mouse also stops responding. unlink(2) call seem to take a long time: $ dd if=/dev/zero of=test bs=1m count=1024 && ktrace rm test && kdump -R | grep unlink 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 2.265 secs (473858546 bytes/sec) 24666 rm 0.000001 CALL unlink(0x7f7ffffbb91b) 24666 rm 0.431070 RET unlink 0 Can anybody provide any pointers on how to debug this further or suggestions on what the problem might be?
