--- Comment #12 from Cenek Zach <cenek.zach@...il.com> ---
I might have a clue. We are changing the limits imposed by HTB each minute
using following command:

$TC class change dev "$BL_DEVICE" parent 1: classid 1:1 htb rate "$LIMIT" burst
"$BL_BURST" cburst "$BL_CBURST" quantum 60000

And this command was definitely running in 3/4 cases at the time of crash
(found him in 'crash> bt -a')
