Re: [PCNET32] Lock solid with netconsole

Hmm, I have been seeing lockups too and asked about doing something
almost exactly the same as this recently, but was told that it shouldn't
need irqs disabled at this point.

Yes. The patch should not be needed.

OTOH, it is still interesting to know if it makes a difference, though
I do not really figure why afterwards (the local irq thread could get
interrupted and the interrupting thread printk() before returning but
I doubt that it is realistic).

Well if it makes netconsole more stable, I think I will try adding it to
and see if it makes the problems go away for good (my problem only happens
at random and can be days between it happening).

One must ensure that pcnet32_{interrupt/hard_start_xmit} do not try to
printk() too.
