Playing midi files finally worked! test3 however is another matter. I can't access my sound device, even though the modules seem to load fine and the card seems to be initialized. This mail is not about that though. After downloading files from my camera, I got an oops when I switched it off and then unmounted it. The oops was followed by a kernel panic and is completely reproducible. Here's the recipe: - boot - login as root - modprobe uhci-hcd (it's not loaded automagically although the module for my pcmcia network card is) -> kernel finds USB ports - switch on connected camera -> kernel finds camera and assigns device - mount /dev/sda1 -> files are visible - switch off camera -> kernel notes that usb device is switched off - umount /dev/sda1 -> oops & panic I've attached the /var/log/messages from boot to panic and also the ksymoops output. /proc/ksym was not present and I do not know how to make it appear, so the ksymoops output is not perfect. Best regards, Jos van den Oever PS I'm not on the list, so for a relatively quick reply please CC me. --Boundary-00=_sNXN/zHU7PgbbDT Content-Type: application/x-bzip2; name="messages.bz2"
