Description

I'm running hrev35763 'bare metal' stylee. If I insert a USB memory stick, choose 'Cancel' when it asks me if I want to mount it (I don't) and then try to zero it with this command:

dd if=/dev/zero of=/dev/disk/usb/0/0/raw bs=1M

I get dumped into KDL land with an error like:

PANIC: vm_page_fault: unhandled page fault in kernel space at ... Thread 27 "ehci finish thread" running on CPU 1

Priority: critical → normal

While certainly not very nice, it's far from critical really. It's an edge case, it'll work with a smaller block size (like 128k).

I had a similar incident when I tried to dd a just built nightly image to a usb drive.
