I'm running the box with a WiFi card, generating lots of network traffic, and the box is running fine, no panics, and low devbuf allocation. I'm running the box with the USB Bluetooth dongle, generating much less traffic (it's just a 9.6kbit GSM link), and the box panics within half an hour in kmem_malloc, with devbuf allocation up to 74MB. It must be either in the Bluetooth code or in the USB code. regards, le -- Lukas Ertl eMail: l.ertl_at_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/Received on Sun Jul 27 2003 - 14:12:20 UTC
