Now, it would be nice if you guys stopped sending stripped down dmesg...
the whole thing is potentially relevant. Also, which compiler version
did you use to generate this kernel ?
Hi Ben, Sorry about not attaching the complete log. Here it is. This is
with git5 kernel.
The machines has an older version of compiler. Here are the details :
# gcc -v
