Hi Tejun,

I don't see that git-bisect session as a time of waste, but two hints:

1. People should sent their patches concerning especially Linux-Next
fixes not only to LKML but also to <linux-next@...r.kernel.org> (if
this is not known, pointing to James).

2. These patches for Linux-Next should contain a "-next" in their
subject-line (use 'git format-patch --subject-prefix="PATCH -next"
...').

Of course, I should have checked the MLs... but for me it was not
clear what was the root cause (which subsystem to blame)... I had only
some suspicions.

Anyway, noone gave me any pointer on how to log bastard logs before my
system got frozen (2nd machine not available).
I know that is tricky!

For a better world...

Regards,
