kernel panic with unloadable module support... SMP

kernel panic with unloadable module support... SMP

[George P Nychis]

Hi,

Whenever I compiled unloadable module support into my 2.6.15-r1 kernel, my kernel panic's when booting up when it tries to load a module for the first time.

I had this problem back with the 2.6.14 kernel, but figured it may have been solved since then so I tried it... and still fails.

Unloadable module support would be very helpful to me.

I am using an intel p4 3.0ghz with SMP support built into the kernel.

Please CC me in your responses.

Thanks!
George

What is 2.6.15-r1 for a kernel?
Is your problem present in an unmodified 2.6.16-rc4 kernel from 
ftp.kernel.org?

If yes, please send the exact error messages.

Okay, I downloaded the 2.6.16-r4 kernel and left it unmodified and I do not get the panic.

Can you suggest anything for me so that I can find what is causing the panic with the gentoo vanilla sources?

Gentoo doesn't understand the concept of "vanilla" packages.  Make a
practice of downloading your kernel directly from kernel.org and
building it yourself.

Out of 10+ boxes that I've run on Gentoo, only one has worked using
the Gentoo kernel.

Uhm, last time I checked, sys-kernel/vanilla-sources was just that -
vanilla kernel.org sources handled by the package manager.

If you check what is in portage currently, there are no 2.6.15-rc or
even _any_ version that have a -rX, so he either used the
gentoo-sources, or he used 2.6.15.1 which had a bug that was fixed in
2.6.16-rc4 (assuming, as there are no 2.6.16-r4 on kernel.org).  No way
to know if he don't specify the correct version, or try the same version
directly from kernel.org (which would probably give the same results if
he really did use vanilla-sources).

Maybe, but did you file a bug ?  No reason for random ranting if you had
issues with their patched kernel.  I can name many other distribution
kernels, and some kernel.org ones that had issues, but then it usually
was my own fault if it stayed an issue.

most of the time that I see this this oops signature the cause is a
mismatch in regparm-ness of a module and the kernel.... (see
CONFIG_REGPARM)

If it was gentoo's vanilla-sources (which is just that - vanilla
kernel.org sources), then no 2.6.x version ever packaged by Gentoo, so
either he had gentoo-sources, which is something totally different (and
not vanilla sources as he specified), or there is a naming issue ...

Re: kernel panic with unloadable module support... SMP

[George P Nychis]

actually, what I am stating is correct, and yes there is 2.6.15-r_ in portage for vanilla-sources:

monster hedpe # emerge -pv vanilla-sources

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] sys-kernel/vanilla-sources-2.6.15.1  -build -doc -symlink 0 kB 

Total size of downloads: 0 kB

That is using ~x86 keyword.

Yup, but its .1 not -r1 ... the official 'stable patch release' or
whatever its officially called done by Greg KH and somebody else.  Point
was that it is vanilla sources, and no real reason for them to tell you
to use vanilla sources, except maybe try a newer version to see if its
fixed already.

Hope that helps.
