Package: cupsys Version: 1.2.7-4etch3 Severity: important Hi
Turning off my laser printer (connected via parallel port) effectively hangs my home server. Whilst hung, the system will respond to pings (reply times in the 20-30 ms range, verses a normal < 0.2ms response), but running jobs are effectively hung (top on the console failed to update for over 5 min, keystrokes on the console are processed at a rate of about 1 per sec), and I can't logon either locally (login via console timed out after 60 sec, but without ever showing the password prompt) or remotely via ssh. Turning the printer back on returns the system to normal. Stopping/restarting cupsys does not clear the problem. The only relevant line in the cups error log appears to be: E [04/Jul/2008:13:51:47 +1000] [Job 232] Back-channel read error - Input/output error! Nothing relevant in syslog or daemon.log. kern.log shows "kernel: lp0: ECP mode" once for every print job. I did power cycle the printer in the middle of a print job when the printer started to print garbage, but have since printed the document successfully. This system was recently upgraded from an old Pentium II to a newer Pentium III by simply moving the hard disks. This is probably the first time I have printed since the upgrade (and hence the first time the printer has been turned on). The old system didn't exhibit the hang when the printer was turned off. I'm hoping that changing the bios parallel port settings might fix the hang locally, but cups / the kernel should be fixed to prevent this problem regardless. I haven't (yet) tried to reproduce the problem after a reboot. I will send a follow-up if I can narrow down the cause/reproduce this. Thanks for your work on Debian.
