Hi!
A bug in kernels 2.4.37.11, RHEL6u7 kernel 2.6.32-573.7.1.el6 found by
using tcc as compiler.
https://github.com/seyko2/tccboot/commit/cee8898165a7bc5aefa8170f6a0290fb2500acf4
Description:
/* Test for the divl bug.*/ must be prefixed by call to the
kernel_fpu_begin().
Bug is fixed in 3.4 kernel. It is present in 3.0.36 kernel.
How to catched:
A tccboot kernel traps sometimes when compiled by tcc. A problem was
before and temporaly solved by reordering of the source file order.
