[9fans] wierd interrupt 0xc6

[9fans] wierd interrupt 0xc6

[west9]

I've been getting this exception for a while now on modem 
downloads longer than about 3min: "wierd interrupt 0xc6" . It appears to be generated by the uart driver:

 grep weird ./*
./uarti8250.c:			iprint("weird uart interrupt 0x%2.2uX\n", iir)

I tried reseating the modem board.

Does this mean I should start looking for a new mother board?

Suggestions, please.

 Thanks

It looks like the handling of 

	Irls		= 0x06,		/* Receiver Line Status */

got lost in the rewrite a little while ago. You could try adding a case for it
in i8250interrupt, lumping it with Irda and Ictoi, i.e.

		case Irda:		/* Received Data Available */
		case Irls:		/* Receiver Line Status */
		case Ictoi:		/* Character Time-out Indication */

That may do, or we might have to split handling the data and error
conditions if it causes problems.

It means you are getting overrun, parity, framing or break interrupts.
