Public bug reported:
I had played a piece of music in Audacity, closed Audacity and two other
program windows when a kernel panic occurred:
"2420.574457 panic occurred, switching back to text console. BUG:scheduling
while atomic: kworker /0:0/0/0x10000300".
I expect that this error message and freeze will not appear.
