Intermittently, printing postscript files to a Lexmark E323
via ulpt0 or unlpt0 will lock the machine. The X session on
the console is frozen, and the machine is unresponsive to the
I have WITNESS and usb debugging compiled into the kernel.
I don't have crash dumps setup, but it does not seem to crash
Tricky. The same file when printed repeatedly will sometimes
freeze, sometimes not. It happens often enough to be annoying.
At home, I switched my lexmark E321 to parallel port, and no
crashes since then. At work I do not have that option.
