Disabling mpsafenet (debug.mpsafenet=0) I run with debug.mpsafenet=0 (due to a bug I ran into some time ago which I haven't looked at recently). The current kernel is running with HTT turned off and no SMP builtin. So kern.smp.disabled=1 is kind of redundant. So no dice on either one of these. > This may be a symptom of a deadlock we're observing on > sparc64 in the network stack.

Warning: Lots of ath debug output. I'm pretty sure it's the ath driver that's the problem, particularly in light of my most recent results. Thanks for the ideas, though. -- Frank Mayhar frank_at_exit.com http://www.exit.com/ Exit Consulting http://www.gpsclock.com/ http://www.exit.com/blog/frank/Received on Tue Feb 22 2005 - 03:02:55 UTC
