Robert, thank you for your fast reply. > If I might suggest, and if possible, you might want to set up a serial > console for the box so that you can copy and paste debugger output. I'll assemble a serial cable and recompile the kernel with debugging components and come back to you as soon as I've got more details on that. > Could you try compiling and running without the PREEMPTION kernel option? I've already build the kernel with SCHED_4BSD but without PREEMPTION (_never_ had PREEMPTION in my kernel config - should I try it?). > A couple of bugs relating to this error were introduced and then fixed. > In particular, could you confirm that you have at least revision 1.165 of > udp_usrreq.c, or 1.162.2.2 of udp_usrreq.c? The merge to RELENG_5 > happened on 8/30 so you should have it, but it's worth confirming. my /usr/src/sys/netinet/udp_usrreq.c has: * $FreeBSD: src/sys/netinet/udp_usrreq.c,v 1.166 2004/09/05 02:34:12 jmg Exp $ > Could you try booting and running the system with debug.mpsafenet=0 in > loader.conf? debug.mpsafenet is already 0 > Is this an SMP box? No, first board had P-III 600 MHz, second had AMD k6/2-500, both single CPU. > Probably the most valuable information would be the stack traces as indicated above, however. Will make the serial cable and come back to you (takes some hours...). Thanks, Volker -- GPG/PGP fingerprint: FF93 13A1 2477 B631 E953 06DF 4C49 ADD9 E4BF 79B1
