Which kernel is targeted?

Following this reasoning to an extreme, since there were already bug reports about 2.6.24
showing freezing regressions for some users, why have I been encouraged by the same distro to
blindly upgrade from the 2.6.22 that gusty had without any warning in the release notes?

On the other hand, given that 2.6.25 is at .9 I would say that it should have received some
testing by now. Maybe it has a larger userbase than 2.6.24. And anyway: I am not suggesting
that all hardy users are forced to upgrade to 2.6.25.9.  I am just suggesting that in one way
or another some kernel that does not freeze is provided.  Maybe 2.6.25 can be provided through
a dedicated channel (e.g. ppa or whatever) with as many scaring warnings as needed.

For what concerns bisecting, I will not do it.  Compiling a kernel takes a night on my slow
host.  Bisecting and testing a bug that causes a freeze every few hours could take a fortnight
or more.  It is just not an option and IMHO is a waste of time since the bug has anyway been
fixed upstream and the kernel developers have moved over. And even assuming that I can
identify the spot to be changed, where is the guarantee that the backported changes do not
cause regressions to other users?  Personally, I feel better using a pristine, vastly tested
2.6.25.9 than a 2.6.24 patched by myself with stuff taken from 2.6.25.9.

But if someone wants host them, I am more than willing to share my kernel image and headers
debs.
