I noted in my original post that if I increase the weight parameter in the driver to have it pull more packets on each poll before taking it break then it takes longer to freeze.
I have looked at a newer version of the 8139cp driver. Very few changes to the poll function; most of them seem to be accommodating changes to the netdevice/napi api. I'll take a closer look at it today. david Avi Kivity wrote: > Avi Kivity wrote: >> david ahern wrote: >>> Almost 7 hours and the uniprocessor case is still chugging along. >>> >>> >> >> How long does it usually take to hang? >> >> How do I go about reproducing this? apachebench (host) against httpd >> (guest) doesn't seem to trigger it. >> > > ab (on host) against httpd (on guest) reproduces within a few minutes. > > uniprocessor guest: works > smp guest: fails > smp guest with one offlined cpu: works > smp guest with httpd pinned to cpu 0: works > > so it's either a guest driver smp problem, or an ioapic problem. > ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
