I have like 8 zombies or something... and some plugin thing is coredumping. the worse thing is that it lets me kldunload linux while those zombies are running and then it panics... this looks very bad. can someone confirm this behaviour: set 2.6 emulation (sysctl compat.linux.osrelease=2.6.16) run opera exit opera ps ax to see if there are zombies left (in my case they were descendant of tcsh - fbsd tcsh) kldunload linux PANIC :) I was running p4 src but I am sure plain -current is vulnerable too. This is a showstopper for the planned switch to default 2.6 emulation in -current. I plan to work on it "soon" (this thursday or weekend hopefully). I already solved all LORs I am aware of so I fully focus on this. I hope to get most of the fixes commited this week (thursday). scott thank you for the report roman
