I recently finished getting printing working under 4.0-RELEASE, but am getting strange behaviour and error messages. I have an HP LaserJet III plugged into lpt0 on irq 7 and the kernel is the stock-standard 4.0-RELEASE GENERIC kernel. (Haven't got around to recompiling yet, as everything so far seems to be OK, except for this, and I also finished installing not long ago). I am running a single standalone machine, connected to other computers only via ppp. I have set up a very simple (but fully functional) /etc/printcap with magicfilter-1.2 as my input filter: spudgun|lp|lj3|hplj3|Hewlett Packard LaserJet III:\ :sh:\ :sd=/var/spool/lpd/spudgun:\ :lp=/dev/lpt0:\ :if=/usr/local/libexec/magicfilter/ljet3-filter:\ :lf=/var/log/spudgun.log: My files actually do print properly, but the *problem* is that I cannot cancel jobs... lpq won't do it, lpc wont't work, kill -9 'ing lpd then restarting lpd doesn't work, neither does turning the printer off then back on again. THe only solution is to reboot the computer. While all this is going on the kernel spits out error messages such as: Aug 15 00:07:33 /kernel: stray irq 7 Aug 15 00:08:02 /kernel: stray irq 7 Aug 15 00:08:28 /kernel: stray irq 7 Aug 15 00:12:34 last message repeated 2 times Aug 15 00:12:34 /kernel: too many stray irq 7's; not logging any more This is what's in my dmesg (but I got it from /var/log/messages): Aug 14 23:07:00 /kernel: ppc0: <Parallel port> at port 0x378-0x37f irq 7 on isa0 Aug 14 23:07:00 /kernel: ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode Aug 14 23:07:00 /kernel: ppi0: <Parallel I/O> on ppbus0 Aug 14 23:07:00 /kernel: lpt0: <Printer> on ppbus0 Aug 14 23:07:00 /kernel: lpt0: Interrupt-driven port Aug 14 23:07:00 /kernel: plip0: <PLIP network interface> on ppbus0 The system is still reasonably "pure". Apart from having installed a few packages like magicfilter, ghostscript, and tcsh, the only way it differs from a stock standard 4.0-RELEASE system is that it I've been trying to set up printing. Any help on this would be greatly appreciated. Andrew Nesbit To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
