spltty / tty_imask question

[Dave Dolson]

A quick FreeBSD 4.7 kernel question:

Is tty_imask supposed to have bits set for all sio devices?

I.e., should bits 3 and 4 be set to indicate IRQ3 and IRQ4?

I noticed by gdb of a running system that bit 4 was set, but not bit 3.

We're seeing a panic due to re-acquiring COM_LOCK, and I was wondering if
this was the problem.

Thanks,
