[parisc-linux] Upgrade path from 0.6 to 0.9?

[parisc-linux] Upgrade path from 0.6 to 0.9?

[Chuck Slivkoff]

I'll be burning a ISO image over the weekend, but I was curious. Is
there the equivalent of "apt-get dist-update" or a simple way to do this
w/ out a complete reload?

On a somewhat related note, the 712 I've been playing on has the 0.6
bits loaded & I've been doing some apt-get's, but right now I can't get
anywhere. I've tried "apt-get -f install" to try to "clean things up",
but keep getting this:

I'm thinking I need to update the kernel, but I'd like to not have to
reload this from scratch.  I can pull the kernel from the 0.9 ISO, but
PALO didn't seem to be too intuitive.

Any suggestions?

You do have to update your kernel in order to run glibc 2.2.3, due to
the changes in how stacks are managed for threads.  I don't think palo
is too unintuitive...

RTFM, I know. I updated the kernel from the ISO image (mounted via
loopback on a RH 7.0 system) and I was able to fix the problem I was
having. I added the ISO image to "sources.list" & have "apt-get upgrade"
running so far without a hitch.

Wahoo!

P.S. The confustion I had about PALO, was wether or not it needed to be
run (like LILO) after changing /boot/vmlinux. The answer, BTW, is "no".

[parisc-linux] Forcing PA-Linux to swap / do_page_fault()

[Chuck Slivkoff]

Greetings all,

I've noticed a problem that I believe is might be related to the kernel
not being able to use swap space.  I've never seen swap utilization > 0
and suspect that something might be seriously wrong. Here's an example
of the kernel error:


do_page_fault() pid=8730 command='Xvfb' type=6 address=0x00000003

My system is a 712/60 with 128MB RAM.

Does anyone have a good example of test to force the system to use swap?

Hmm... none of my systems are using swap either; I had noticed this before,
but never really thought much of it.  This has to be a moderately recent
breakage because I know jsm has tested swapping.

Sure.  malloc 256MB, then dirty each page.

I noticed similar behavior w/ the kernel from the 0.6 ISO, but it's been
behaving much better since upgrading to the 0.9 bits.
