Message-ID: <3F14151D.9010205@byu.edu>

Hey,
Got the latest kernel and figured out that having hdb=ide-scsi as a boot 
paremeter was causing the kernel to freeze in the middle of IDE 
initialization. I have been trying to figure out what the problem was 
ever since about 2.5.25.
    The main problem I have noticed so far with 2.6 is that my xterms 
won't open properly. For example with the gnome terminal, the window 
opens and everything looks dandy, but no prompt appears. Does this have 
anything to do with the reorganization of the device systems ? Do these 
apps need to be recompiled, or just reconfigured, or am I missing an 
important module from my kernel?
    Oh, I have also noticed that the 'responsiveness' in xwindows is 
much improved, probably thanks to the preemptible kernel option.
    Later!
    - Josh

If you really want preemption, I recommend you just patch your 2.4
kernel until your distribution officially supports the 2.6 kernel.  If
you are prepared to submit bug reports and suffer data loss and kernel
panicks, then use 2.6-pre*.

There are some really cool things in the 2.6 kernel (my personal
favorite are the Linux Security Module (LSM) hooks - I'm actually
writing an LSM to implement BSD Secure Levels at the moment ;-).  When
you can apt-get install kernel-2.6 from the Debian testing branch,
then it will be ready for prime-time.

The Linux kernel was originally built on the 32-bit x86 platform.  It
has been ported to many different architectures since then.  It runs
pretty well on current IBM Power chips, but the LTC is now dedicated
to getting it to ``world-class'' status on Power4 (and future 64-bit
Power chips).

It will be a glorious day indeed when I chuck my x86 chip in favor of
a real architecture.  Expect to see some cool stuff happening with
Linux and the Power4 and Power5 chips in the coming year.  My next
desktop PC may very well be a dual-processor G5... ;-)

3 months at big blue and they've already got him talking Power PC over
all the rest.  Hey, I heard somewhere that IBM makes IA64 chips too (or
maybe they just sell them).  And what about those 64 bit AMDs?  Which 64
bit chip is it going to take over?  My guess is not the one that only
Apple backs :)

Oh, that's easy, Bryan.  It will be the one that best runs GNU/Linux,
of course!
