I have 100% reproducable trap 12 panic in kernel. I thouhgt it appeared
somewhere after 5th of february, but i was wrong. The problem is that when
i try to compile something with "make -j 2" - it panics and i can't
backtrace the first fault point. :( If i simply use make, i have a chanse
to build and install this something.
So what am i doing wrong? How can i solve this problem? Any help?
Here is dmesg, config and gdb -k output:
