[2.5.54] OOPS: unable to handle kernel paging request

[2.5.54] OOPS: unable to handle kernel paging request

[Steven Barnhart]

Hello,

I seem to get a very nasty oops exactly when booting 2.5.54. When i
boot to the kernel I immediately get a kksymoops report flooding my
screen. This happens to fast that the text blurs and basically everything
stays where its at. There is no way to stop it except rebooting. I do not
have any serial connections to send the output to so I got (hopefully) the
most important line. The oops says "unable to handle kernel paging
request at virtual address ffffff8d (there may be another 'f' in there). I
searched through the archives and their seems to be a few oops reports of
the same kind but no patches and the only kernel was 2.5.48-bk I think.
Any thoughts?

Got the same yesterday evening when installing 2.5.54 for the first
time....

My second PC which I used for Serial console was not at home,
so if a console output is needed, people will have to wait
for the weekend (which is not that far).

Config was roughly including :
 - Arch = P4, Unipro, APIC
 - CPU Freq scaling
 - ACPI (enum only)
 - TCP (v4 + v6), Netfilter
 - IDE, SCSI (AIC7xxx),
 - Sound (Alsa, EMu10K1),
 - Crypto

This oops happens at the very early stage of the boot process.
By that time, only 10 to 15 lines are displayed on the screen
following the "Booting ...................." stuff.

Check if the processor in your .config matches with the processor that you have.
Eg. Problme might arise if .config file says CONFIG_MPENTIUMIII=y when your processor is P4.

Nope, it was really configure as P4, and I really have a P4.

Might, but I have the same thing, and I copied my 2.5.53 config and did
oldconfig. Got a perfect build, it just doesn't boot. The snow is falling,
I'm likely to have time to look at it this weekend.

Well I have a Intel Celeron 1.06 GHz (i686). 384MB ram, gcc 3.2 (redhat
8 release). I don't really know how to decode it since I have no serial
console hookups...anything paticualr I could get from the oops report
during bootup? i.e. what sections to copy?
