Just tried that dnet patch on my ASUS P2B-LS "S3 suspend-to-ram" test box,
but it's crashing the box with a failed assertion panic during driver resume:
assertion failed: mutex_owned((&dnetp->intrlock)), in file dnet.c line 2308
stack backtrace shows
:panic...
dnet:set_sia+12c(...)
dnet:dnet_init_board+2a(...)
dnet:dnetattach+5bd(..., 1)
...
(messages manually copied, disk device is suspended, so no crash dump :-)
I think the "dnet_init_board(macinfo);" call in the dnetattach()
DDI_RESUME case should be moved after the mutex_enter() calls.
With that change, suspend / resume does not panic any more.
But the dnet device seems to be dead after a resume. And after maybe
a minute, I got another panic when I tried an "ifconfig -a" after the
resume:
