>Description:
I have an EVDO Cardbus card that is actually a umodem connected to
a USB hub which is on the card. When I insert it with a kernel
built from Sunday's -current source, the system panics:
supervisor trap double fault code=0 in pid 7.1 (cardslot0),
usbd_get_string+0x17. The back trace is quite long and I have
no way to capture it; my laptop doesn't have a serial port.
Here's output from a working insertion on a May 13 kernel:
