Lock /mutex issue with i916 on HP620
to help debugging the Wireless stuff with Christos on my HP620, I
compiled a kernel with DEBUG+LOCKDEBUG.
The kernel does not complete booting! it stops with a turnstile issue
and a LOCKDEBUG bug.
Mutex error: lockdebug_wantlock: acquiring sleep lock from interrupt context
<.. hex details>
Turnstile chain at 0xffffffffff8101900.
=> No active turnstile for this lock
panic: LOCKDEBUG: Mutex error lockdebug_wantlock: acquiring sleep lock
from interrupt context
the stacktrace clearly shows it inside i915 / i965 code
I was able to take a screenshot with a ddb stacktrace. I canno t attach
them here apparently, where may I post them (some pastebin but for
images) / send them in private ?
