I have been trying out USB serial devices on RELENG_5 to see if they are a workable replacement to PCI cards. Unfortunately, it seems fairly easy to hang such a device. (full dmesg below) I have a 28.8 modem connected to a ucom device Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 addr 2: full speed, power 100 mA, config 1, PL2303 Serial adapter (ATEN/IOGEAR UC232A)(0x2303), Prolific Technology(0x067b), rev 2.02 port 2 powered I start up a ppp session using it with the speed set to 57600. I then start up a ping -s 512 pinging something on the other side. I then kill the connection from the terminal server side to simulate a dialup modem failure. The pings build up to the point where I get "no buffer space available" and then a few dozen putc to a clist with no reserved cblocks putc to a clist with no reserved cblocks putc to a clist with no reserved cblocks putc to a clist with no reserved cblocks putc to a clist with no reserved cblocks putc to a clist with no reserved cblocks putc to a clist with no reserved cblocks fill up the console. At this point, ppp is totally hung, and I cannot kill ppp [releng5-865]# ps -auxwwjl -p 718 USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND PPID PGID SID JOBC UID CPU PRI NI MWCHAN root 718 0.0 0.9 3292 2340 ??
