Hi Tony, I tried your patch to drivers/serial/8250.c and it works fine. I was concerned that I would start seeing: omapfb: omapfb blah blah interrupt 0x4000 (sorry, can't remember the exact verbage) because I saw them at one point during the many reboots I did while working on the serial port problem. But I didn't see any after about 20 reboots. I assume you mean the patch below but why do you want this one if your 8250.c patch works?
