Hi, just another kernel panic: it may be due to a buggy IBM USB keyboard with integrated touchpad. I got random generation of ESC ^G characters. When unplugging this keyboard from the box for the second time, I got the following panic (admitting that it doesn't look like a keyboard related crash): [root@ /var/crash]# kgdb /boot/kernel/kernel ./vmcore.11 kgdb: kvm_nlist(_stopped_cpus): kgdb: kvm_nlist(_stoppcbs): [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Unde fined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
