Hello,
just another locking bug, I wonder if this wasn't discussed yet, but I can't
find it.
============================
[ BUG: illegal lock usage! ]
----------------------------
illegal {hardirq-on-W} -> {in-hardirq-R} usage.
events/0/8 [HC1[1]:SC0[0]:HE0:SE1] takes:
(hl_irqs_lock){--+.}, at: [<f88e4e09>] highlevel_host_reset+0x15/0x63 [ieee1394]
