The following reply was made to PR kern/21929; it has been noted by GNATS. From: Paul van der Zwan <paulz@trantor.xs4all.nl> To: freebsd-gnats-submit@freebsd.org Cc: wkwu@csie.nctu.edu.tw, jhb@freebsd.org Subject: Re: kern/21929: lpd cause system crash Date: Sun, 22 Oct 2000 11:26:45 +0200 I am having the same problem, code in inthand_add causes a trap 12. This happens regularly when printing a file. I also noted that when I run systat -vm some interrupt vectors are marked as stray and used by a device. Look at irq 0 and 6 in the output below. Might this be related to the changes in intr_machdep.? made in september ?? I never had these panics before I built and installed a new current about 3 weeks ago.
