>Well a few minutes ago my system went into deadlock - and this is with the >kern_lock.c dated 5/11. This patch is different than the one in 8416 that >solved my problem before. I'd say this the problem is still there. Time is very short for getting this fixed before the release deadline. I think Luoqi's patch that was in the PR was suseptible to a priority inversion problem and has risks associated with using it. The fix that Matt Dillion made for -current that I back-ported to -stable was an attempt to fix the problem while minimizing the side effects. If it doesn't fix the problem then we'll proceed with plan B which is probably to just go with Luoqi's fix or to possibly troubleshoot Matt's fix (but as I said, time is short). >Once again my server is useless, deadlocked.
