Hi,
I recently ran into problem where I needed a stacktrace to figure out
why EHCI - USB path (usb_allocmem) is not working and I couldn't get
access to ddb console because the keyboard was unusable.
I finally found out I could do the print like below and it gave me a
usable stacktrace.
That 'cold' condition doesn't work for some reason (can BIOS/OS give
indication it is cold boot?). Anyway it is much better to give a
stacktrace to user so that they can give it back to developers.
If nobody has objection can somebody please commit?
Thanks
