The following reply was made to PR kern/152310; it has been noted by GNATS. From: Stacy Millions <stacy@Millions.Ca> To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/152310: [uart] [hang] Serial I/O hangs in FreeBSD 8.x Date: Sat, 12 Feb 2011 21:43:02 -0700 I have a similar problem with ntpd talking to an Oncore GPS. It will run for a few hours or a few days, but then the serial port will freeze up. Only a reboot will reset things. This hardware combination worked fine for years running 6.x, it was only after I upgraded to 8.1 that I had this problem. I have just built a kernel without the uart driver in the hopes that unloading and loading the module will allow me to reset things without rebooting. uname: FreeBSD oak.millions.ca 8.1-RELEASE-p2 FreeBSD 8.1-RELEASE-p2 #0: Thu Dec 2 11:50:22 MST 2010 root@buildhost.millions.ca:/usr/obj/usr/src/sys/GENERIC amd64 dmesg: uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 uart0: [FILTER] -stacy
