>Description:
I have a program that opens a usb temperature device via the
ugen driver, and after a "while" (anywhere from a day or two up
to two or so weeks) I get the following panic (via ten finger
copy):
uvm_fault(...)
fatal page fault in supervisor mode
trap type 6 code 0 ...
kernel: page fault trap, code=0
..
ohci_free.std.clone.3() at netbsd:ohci_free.std.clone.3+0x17
ohci_device_ctrl_start() ...
usbd_transfer() ...
usbd_do_request_flags_pipe() ...
usbd_do_request_flags() ...
ugenioctl() ...
cdev_ioctl() ...
VOP_IOCTL() ...
vn_ioctl() ...
sys_ioctl() ...
syscall() ..
db{1} >
Note that the USB keyboard doesn't work in ddb, so please
don't ask for more from ddb unless I can squeeze it into
ddb.commandonenter.
>How-To-Repeat:
Repeatedly open a ugen device?
>Fix:
Non given.
