Hi, I updated from Dragonfly_Stable from about 3 weeks ago to HEAD and the serial port seemed to stop working. I get: sio1: can't drain, serial port might not exist, disabling I #ifdef'ed out that check from sio.c 1.17 and even though it registers the sio device still no data (it's a NMEA GPS). I also reverted sio.c to 1.20 with the drain check, still nothing. Hmmm... I'm just looking through old dmesgs now and I see that I even got the can't drain message before, but it still worked. Wierd. Anyway, this is a plain old 16550A on an Intel i810E motherboard so it's not exotic or anything. I don't mind poking around trying differet revs -- anyone have any tips on what to try? -Paul.
