Hi John!
I would like to give you some more hints and feedback to find
the "freezing" bug :-) I'm know testing the SMP-kernel since
20th Jan almost every day, and I have the same problem all the
time: Running X and under heavy load the system freezes, the screen
doesn't update anymore, the mouse freezes a few seconds later
and ca. at the same time the disks stop working. There is no
panic (I'm using a COM-Console) and I can't call the DDB, only a
ping still works. My machine is running very stable under FBSD-stable
(of course :-) and relativly stable with an old kernel from december.
I can't reproduce the freezing X-bug with an old SMP-kernel!
To reproduce the X-freeze I'm compiling a kernel with -j10 in the
background, running some java applets with the new jdk1.1.5 port
(which is very nice btw) and an xv showing some jpegs in an automatic
loop. Under this load, the system freezes after only a few minutes.
Under normal load I can work for many hours without a crash
(I'm doing some java-development with xemacs, hotjava, netscape und
jdk1.1.5)
With your speed improvements lately I can run make buildworld now
in less than an hour (options: -j8 -DNOPROFILE -DNOCLEAN -DNOTCL,
/usr/src and /usr/obj on different disks (sd1 and sd2) mounted
with async and noatime option), great work!!
