I'm rebooting with that patch right now.
I added the patch, and tried it out. When the network hangs, I am able to revive it

How about using fcntl(), O_ASYNC and SIGIO?
Don't think that's supported for disk files yet, at least by the

Or maybe a broader question:

As per Linus' suggestion, I removed the disable_irq/enable_irq statements from
