Subject: [Regression] Crash in load_module() while freeing args

Date: Tuesday, May 25, 2010 - 2:00 pm

Hi,

Recent -git kernels crash for me quite often during boot, reporting that kernel
paging request could not be satisfied at load_module+0x18e4, which
corresponds to line 2483 of kernel/module.c for the kernel in question (however
the same call trace says IP is at precpu_modfree+0x1 at the moment of the
crash, which seems to point to line 2481 of the same file).  It doesn't happen
every time, but it does happen often enough to be annoying and the call
trace is always exactly the same.

I'm going to revert post-2.6.34 commits that touch kernel/module.c directly
and see what happens.

Thanks,
Rafael
