Hi guys, You remember my problem with 1GB of memory on my A7V8X card, vga=788 and kernel compiled with high mem support (2.4.21-0.13mdk enterprise) combination ending in a kernel oops.
I did my best to learn about tracing stuff in linux / linux kernel and I patched the kernel with the kmsgdump and also installed ksymoops. I set up kmsgdump to do an automatic dump on floppy in case of kernel oops. I attached the resulting messages.txt and also the oopsresults.txt as the result of running ksymoops on the messages.txt There is a warning in it which says results might not be reliable because of some module mismatch, but it is ok. The oops had nothing to do with that module. So make abstraction of it. The pwcx-i386 is compiled for some other version but it works and I need it for my webcam. It appears in the result of the ksymoops but at the moment it crashes (right at boot) it doesn't even get to the point where it has anything to do with the modules. Can anyone tell me if any kernel guru can understand any of these results? Is there a specific place where I must send the results for interpretation? If anyone needs more info please don't hesitate to contact me by email. Best regards, Adrian P.S. I also added the ioremap.c and the ioremap.s (compiled for debugging) so maybe people would have all the info in order to understand what happens. :)
