I tried the patch, but it still panics in the same place.
I think the actual call path causing the panic is
eso_attach() -> eso_reset() (inlined) -> eso_write_mixreg()
but in addition to that, it looks like eso_attach() also calls several
other functions that assert that intr_lock is held without actually
holding it: eso_set_monooutsrc(), eso_set_mopnoinbypass(),
eso_set_preamp(), and eso_set_recsrc().
