When I moved from Fedora 13 from Fedora 11, I thought the annoying application crashes that I had been having were gone for good. But they have come back to ahunt me .. random crashes - firefox, Thunderbird, Abrt, metacity and what have you with SIGSEGV errors.
I'm beginning to believe that these are not down to Fedora or even the RAM (Have run Memtest, several times). I'm not sure if what I am seeing are signs of IRQ conflicts of some sort. Can someone, please have a look and give me some guidance on what to do? Should I reinstall with acpi=off ? noapic? or something else?
Also, don't have a clue why the system complains of ECC being disabled? The RAM is non-ECC.
I have posted some sections of the logs here with links to the full logs instead of making this a massive post.
