I cvsupped RELENG_3 last night (about 20 hours ago) and after making world
last night I built a new kernel this morning and rebooted. First thing I
noticed is that my splash screen caused the video controller to go
strange (made the monitor sing as well). Then within a couple of minutes
the machine had rebooted. I rebooted and bypasssed the loader to remove
the splash screen. Within a couple of minutes I got a page fault while
in supervisor mode (write to page not present). The machine is SMP
(dual P133MHz) which may make a difference. My home machine which is
running a very similar vintage has been stable. Since I can repeat this
I'm going to try getting a crash dump. However I suspect that anybody
else running SMP will find it similarly easy to reproduce.

Has anybody else noticed the IDE disk flackyness lately? One one machine
I have a ccd mirror, and on another machine a vinum mirror. If I hit
these filesystems heavily it's a garantee to lock, no panic, virtual
console switching works, ping works, but everything stops. On the ccd
mirror machine I backup the root filesystm using dd, it's completely
reproducable to lock the machine by dd from rwd0s1 to wd2s1, the file
stats by dd get printed but I never get a prompt back.

I think the -stable tag went on way to early.

Cheers.
