Hi. I'm seeing a -current from about three days ago panic continuously, and I can't seem to figure out what it is. I assumed it was related to the whitespace issue (/usr/src/sys/kern/imgact_shell.c), for which a patch was committed recently, but I'm still seeing panic's after re-building world and kernel. A machine built with the same sources is behaving correctly, but is under much less load. Attached are the necessaries; any pointers would be greatly appreciated. This is on a system that was cvsup'd, worlded and new kernel installed last night (around 20h00 GMT+00). bash-2.05# kgdb kernel.debug -c /var/crash/vmcore.0 kgdb: multiple core files specified. Ignored kgdb: -c: No such file or directory bash-2.05# kgdb kernel.debug -c /var/crash/vmcore.0 bash-2.05# kgdb kernel.debug /var/crash/vmcore.0 [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
