RE: Woody is bootable? (was: Sarge is bootalbe?)
The version of UNIX I am accustomed to comes with SMP enabled by default. I
didn't realize there was an SMP package for Debian until I had started the
kernel build. Like you, I didn't read everything I should have before I
dived in. Since I had linked in everything I wanted in addition to SMP I let
the build run to completion. With 8 processors and 4GB memory (and support
for 8GB), I assumed the compile would run faster than that even though it
was only using one processor. I guess certain concessions were made that
degraded uni-processor performance in the machine's architecture.
No flames are justified. All of us have different levels of expertise and
expectations. You think X configuration is fun on servers, try it on an
older laptop.
Thanks
Rick

No problem with the kernel afaik: I didn't build it though. After
forcing the upgrade from potato and spending hours tweeking X, ALSA, and
practically everything else which wasn't quite working, it seemed to go
perfectly. Things went faster with the stock SMP kernel than the single
processor one, and I guess there may be some advantage to building a
custom one, but I didn't bother being so relieved at getting the
potato->sid transition going at all. With make -j (not on the kernel,
but on a reasonably sized project I work on from time to time) the
machines really fly. Mind you, with 2GB RAM, you'd expect reasonable
performance.
Next time I'll read the manual. Thanks for being patient, Rick and Mike,
I deserve a good flame for that piece of stupidity!
The only time I've been seen the behaviour you describe w.r.t. strange
slow-downs, Rick, it was to do with a bizarre series of coincidences to
do with an automounted filesystem and conflicting IP addresses. Always
had pretty close to pinned CPU utilization.
