My old 1.5.2 kernel had
options       BUFPAGES=800

I tried recompiling the kernel using
makeoptions     COPTS="-mcpu=604e"
options         BUFPAGES=2048

It didn't work. The system would hang during boot as soon as it came to 
file system checks. Okay so I tried
makeoptions     COPTS="-mtune=604e"
options         BUFPAGES=2048

Still didn't work. I really wanted -mtune to work so I tried
makeoptions     COPTS="-mtune=604e"
# options       BUFPAGES=2048

Still no go. I am recompiling one more time with no COPTS just to make sure 
with
# makeoptions   COPTS="-mtune=604e"
options         BUFPAGES=2048

because I don't really see a reason why the higher bufpages should cause a 
problem. It would be nice to be able to turn on those compiler options and 
get a more optimized kernel. Has anyone had success compiling with those 
before?
