I'm too seeing these annoying kmem_malloc panics on recent -current kernels. The laptop I'm using is way off of being overloaded at all, the only thing I do is going online using a Bluetooth USB dongle. As soon as I generate some network traffic, devbuf allocations go up, until at some point the machine panics randomly in kmem_malloc. I have different core dumps and backtraces available, but they don't seem to be of much use in this case. I really suspect the USB stuff to be leaking. regards, le -- Lukas Ertl eMail: l.ertl@univie.ac.at UNIX Systemadministrator Tel.: (+43 1) 4277-14073 Vienna University Computer Center Fax.: (+43 1) 4277-9140 University of Vienna http://mailbox.univie.ac.at/~le/
