I can terminate all faxing processes, reset the modem and attempt to re-initialize it without any luck. It does not respond at all until I reboot the server. I found pr kern/140947 which is a very similar report and have verified that I am using puc/uart updated beyond this point. murgo% pstat -t LINE INQ CAN LIN LOW OUTQ USE LOW COL SESS PGID STATE sysmouse 0 0 0 0 0 0 0 0 0 0 - ttyu0 0 0 0 0 0 0 0 99999 0 0 IC ttyu1 0 0 0 0 0 0 0 13 0 0 IC ttyu2 0 0 0 0 0 0 0 11 0 0 IC ttyv0 1920 0 0 192 1984 0 199 1712 49247 49247 Oicl ttyv1 1920 0 0 192 1984 0 199 19 49245 49245 Oil ttyv2 1920 0 0 192 1984 0 199 7 49244 49244 Oil ttyv3 1920 0 0 192 1984 0 199 7 2228 2228 Oil ttyv4 1920 0 0 192 1984 0 199 7 2229 2229 Oil ttyv5 1920 0 0 192 1984 0 199 7 2230 2230 Oil ttyv6 1920 0 0 192 1984 0 199 7 2231 2231 Oil ttyv7 1920 0 0 192 1984 0 199 7 2232 2232 Oil ttyv8 0 0 0 0 0 0 0 0 0 0 - ttyv9 0 0 0 0 0 0 0 0 0 0 - ttyva 0 0 0 0 0 0 0 0 0 0 - ttyvb 0 0 0 0 0 0 0 0 0 0 - ttyvc 0 0 0 0 0 0 0 0 0 0 - ttyvd 0 0 0 0 0 0 0 0 0 0 - ttyve 0 0 0 0 0 0 0 0 0 0 - ttyvf 0 0 0 0 0 0 0 0 0 0 - pts/1 0 0 0 0 0 0 0 12 57369 0 G pts/0 0 0 0 0 0 0 0 0 78315 0 G pts/2 1920 0 0 192 1984 0 199 7 45529 45534 Oi murgo% dmesg | grep uart uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 uart0: [FILTER] uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0 uart1: [FILTER] uart2: <16550 or compatible> port 0x3e8-0x3ef irq 5 on acpi0 uart2: [FILTER] >How-To-Repeat: Using cuau0 for an hour or so seems to repeat the problem for me. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
