Can you be more specific as to the 'bad things'?
Not very. Maybe interrupts don't get reenabled as intended. Then the
symptoms get mutated by watchdog timeouts.
Then yes, I'm already thinking of a better way to do the interrupt
enable/disable thing. I am still very surprised that the hardware
cannot be silenced by doing a read and/or write of a status register,
like most other hardware. If that were possible, this would be a very
simple problem.
Er, what is it that em_disable_intr() disables?
The problem might go the other way, being that em_enable_intr() doesn't
always work due to the device not liking high frequency toggling of the
interrupt mask register.
