2.6.31-rc8 i got dmesg flooded. First message appearing even without patch, i 
will make sure now what is a reason of that (i have HTB classes on ifb0, and 
TBF on pppX).

[  155.199923] Attempt to kill tasklet from interrupt

We know the reasons for this message, it's an HTB regression and we're
working on it.

There is a few more than HTB. Btw, IMHO, we don't risk much (if at
all) if we revert this qdisc_watchdog change. There is still CBQ
problem, where we could probably reconsider Thomas Gleixner's first
attempt with additional locking and irq disabling as a temporary
solution?
