Since years it's all the time that I compile the kernel with everything
enabled, because these kernel builds are for a distro, and should work
on any computer. Normally, things going stable at -rc3 or -rc4 , often
already at -rc2.
Beside of with my computer, essentially the same problems also happens
with a laptop of a friend.
Also, a big problem are the (after-boot-) crashs if zipping / unzipping
big files. Packages I can build only with 2.6.38.4, not with 2.6.39-rcX
Below is the diff between the config of 2.6.38.4 and 2.6 39-rc5-git3 .
You could inspect them what potentially could explain the reported
problems. But I think at least the problems which happens on my
computer, and on that of the friend, are regressions, because none of
the new staging drivers we use.
