Some problems with 2.6.13.4

Some problems with 2.6.13.4

Hello!

With 2.6.13.4 I've problems on several machines:

- IBM Thinkpad 600: Hangs (no panic, simply dead) after HDC (cdrom)
  is initialized [Works with 2.6.13.5]
- Dell Latitude C400: Keyboard does not work
- new HP-Servers (ML-350): Hangup when syslog is started

What information do you want to have from those machines?
lspci, dmesg, cpuinfo, .config when running with older kernels?

The kernel configurations are used from the versions before, with running
make oldconfig before.

Greetings,

Nico

so, these machines were running fine with 2.6.13.3 or .2 and stopped
working with 2.6.13.4? if yes, then perhaps you can narrow it down to one
of the changes in patch-2.6.13.3-4.gz or patch-2.6.13.2-3.gz

Sorry, I sent the message before inserting this info:

- ibm tp runs with 2.6.12.5
- dell latitude runs with 2.6.10

I personally have access to the ibm tp and I'll test 2.6.13.3 in some hours
(which it nees to compile it).

I'll report more info than. Perhaps Daniel Aubry can test on his dell, too.

I was a little bit wrong:

2.6.13.3 and 2.6.13.4 freeze both on the ibm tp 600, but first
after "Freeing unused kernel memory: 96k"

There is no output from init (neither "cinit-0.2: Booting from ..."
nor "INIT:" (sys-v-init)), so this is not an init problem.

Could we somehow debug this differently or do I have to install
2.6.13.2 and 2.6.13.1, too? It would take simply hours until it is
finished here.

If you have another, faster, machine available you could build the
kernel(s) on that one. You don't have to build a kernel on the same
machine that is later supposed to run it.
Also, if you have more than one machine (even if they are not
especially fast) then you can use distcc (http://distcc.samba.org/) to
distribute the build over multiple machines which can speed up a build
a great deal.

Actually, one of my fastest machines is this one:

bruehe2# cat /proc/cpuinfo 
[...]
model name      : Pentium III (Katmai)
cpu MHz         : 551.280
[...]

And one, which has a not-so-good connection to me.

That's clear :-)

distcc will fail here, because of different gccs and different distributions
(ever tried to use gentoo and distcc in the same distcc-network? It's a real
pain).

Thanks for the hints anyway,

Nico

You can also use ccache to speed-up:

After some heavy compile hours, here are the results:

- 2.6.13.1 and 2.6.13.2 behave the same way with the same config.

For reference I now published the configs [0]. 2.6.12.5 was the config
source, all others where generated using make oldconfig.

Perhaps there's a somehow heavy configuration mistake in it?

Btw, Daniel Aubry fixed his keyboard problem with disabling usb keyboard support
in the bios (is this really the right way?).

How come?
I am using distcc + ccache in default install with at least -j5 on my network of Gentoo machines.
And building a kernel with -j8 on 4 boxen (P4@2GHz each) is a snap.
Particularly pleasing to watch distccmon-gui :-D
