Is this backtrace from a hanged, unusable kernel or ? A pause is _not_ perfectly fine, even not to some extent. That pause we are discussing about is a pause of the _whole_ machine, not just disk i/o pauses. Mouse stops, keyboard stops, everything stops, who knows wtf.
That behaviour is absolutely bullshit for desktop users. For serverusage you may not notice it in this dimension (mostly no X so no mouse), but also for a server environment this may be very bad.
ciao, Marc
