patch for timer.c - two dmesgs

patch for timer.c - two dmesgs

[Uwe Bugla]

[-- Attachment #1: Type: text/plain, Size: 1608 bytes --]

Hi Roman,
Trying to boot kernel 2.6.18-rc1-mm1 on a Siemens-Fujitsu mainbord with an Intel Pentium 3 processor running at 600 Mhz the last message I can read is the following:
Starting PostgreSQL 7.4 database server: main_
(The _ behind main stands for the hanging cursors).

Then the boot process does not take any break at all (like in kernel 2.6.18-rc1 and in kernels 2.6.17-mm*), but simply stops completely.
About 7 message lines are missing before X starts for presenting the graphical login prompt (proftpd, xprint etc.).
Perhaps two dmesgs help: one for a functionable 2.6.17.4 kernel (dmesg17), another for the kernel in question (dmesg18).
This does not happen on two Pentium 4 machines with Asus mainboards and Pentium 4 processors running at 1800 Mhz.

Please see two dmesg attachments.

Regards

Uwe

P. S.: Please a humble request: I'd deeply appreciate that Valdis stops telling me things like: „Odd.. there wasn't anything P4-specific in that patch..“ or
„Are you *positive* that your Pentium3 box is hanging up for the same reason? It could be it's something else entirely.“

Simply my intuition tells me that a system timer performs very different on two very different machines with two very different CPU frequencies and two very different main processors.
For example absolutely NO Pentium 3 or Pentium 2 processor contains hyperthreading technology, far apart from the totally different CPU frequencies!
In so far it not only could be but simply MUST be a timer.c issue!!

A lot has changed since then...
Did you try using SysRq+P or Alt+ScrollLock? (A SysRq+T might be useful 
too).

No offense, it's no intuition, but a shot in the dark.
If you at least tried a few more kernels (at least 2.6.18-mm1 and 
2.6.18-mm2), it would be a much better indication whether it's the timer 
patch.

Sorry for this stupid sounding question:
At what point of the boot process do I have to use those keyboard combinations please? And what is the output / product of them please?
Sorry if I simply lack experience in those questions.

Just press them the boot stops and send the kernel log or wite it down if 
it's not in the log.

This might help : http://sosdg.org/~coywolf/lxr/source/Documentation/sysrq.txt
I can't answer at what point you should get the data though.

Thanks, Roman.
To avoid misunderstandings:
I in fact invest more time and energy in testing mm- or other kernels than any comparable user or admin. I in fact tested 3 or 4 different ones somewhere between 2.6.17 and 2.6.18-rc1-mm1, but got exhausted and demotivated as the only output was inability to boot.
I informed Andrew as quick as possible. And I never in my life stumbled over kernels behaving like this. In so far as a consequence I am missing tools or tricks how to produce system output for constructive feedback.
 Question: What difference is there between the output of dmesg when kernel stops out of inconvenience or just out of containing buggy code on the one hand and the output of SysRq+P or Alt+ScrollLock on the other hand?

Regards
Uwe
