As usual, I did csup, rebuild kernel & world, installs and reboot. After I plugged an USB stick, the kernel panics. I tried at another machine, which has been configured newly from the scratch - there the umass plug in doesn't crash the machine. The machines differ in hardware configuration - the crashing one is a Intel configuration (Dual Xeon), the non-crashing an AMD/VIA chipset based notebook. If my kernel configuration would help, I'll send it in a separate mail - but I hope the backtrace is more helpful. >How-To-Repeat: >Fix: Patch attached with submission follows: GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
