>Description:

I normally wouldn't report a bug on a kernel this out of date, but it's the
first time I've ever seen it, and I may never see it again.  The message
"vm_pageout_scan: page not inactive?" was repeatedly printed, and the system
hung.  This kernel has been running for ~ 2 weeks without any problems, the
only unusual thing was a modem hangup (ppp), only a few seconds before this
problem erupted.  Here is an exerpt from syslog:

Jun 17 20:42:08 xi pppd[232]: Hangup (SIGHUP)
Jun 17 20:42:09 xi pppd[232]: Modem hangup
Jun 17 20:42:10 xi named[65]: ns_forw: sendto([128.8.120.50].53): No route to host
Jun 17 20:42:10 xi named[65]: ns_forw: sendto([192.112.36.4].53): No route to host
Jun 17 20:42:40 xi /kernel: vm_pageout_scan: page not inactive?
Jun 17 20:43:12 xi last message repeated 203 times
Jun 17 20:43:14 xi last message repeated 291 times
Jun 17 20:43:14 xi /kernel:  not inactive?
Jun 17 20:43:14 xi /kernel: vm_pageout_scan: page not inactive?
Jun 17 20:43:15 xi last message repeated 112 times
Jun 17 20:43:15 xi /kernel:  not inactive?


>How-To-Repeat:

 That problem *very* well understood, and has been fixed in the pageout
 daemon.  It was a very very tricky problem.
 
 Thanks!!!
