Description Steve 2006-09-20 22:26:34 UTC
Description of problem:
It has come to my attention that the kernels availble for upgrade with Fedora
could be better -- they sometimes don't even work. While a bugzilla could be
filed on each individual event that occurs for each kernel, I think it may be a
better idea to try and do what it takes to get major kernel errors from updates
down.

Version-Release number of selected component (if applicable):
I stopped using Fedora packaged kernels because updating the kernel was never a
known of what the result would be. EX: will I get a kernel panic, will my
ethernet not work? and while a user can boot to the old kernel easily, still i
think its something to consider.

How reproducible:
When I used Fedora kernels, updates were not always a garantee of working. There
were quite a number of Fedora kernel updates that gave me kernel panics and
others caused my ethernet to be broken.

for instance here's two forums on fedoraforum which imply kernel panics with
latest kernel - 2.6.17-1.2187_FC5
http://forums.fedoraforum.org/showthread.php?t=124820

Steps to Reproduce:
1.
2.
3.
  
Actual results:
Fedora Kernel updates can cause kernel panics and other unwanted errors

Expected results:
Kernel errors in general should try to be reduced especially if its a kernel
panic or causes something like ethernet not to work.

Additional info:
While its just natural that there will be issues as code is changed in
kernel.org's upstream and eg when Fedora adds patches to help do X or make
kernel better in some way. Either more time needs to be spent testing the kernel
or more time needs to be taken to look through say the kernel config and added
patches to try and limit kernel panics and undesired results from upgrading to a
new fedora kernel.

There are many reasons regressions can occur, and dealing with them on a
case-by-case basis is the only way.

If there was a quick one-size-fits all solution to everyones problems, we'd have
implemented it already.

Of the two reports you reference above: The first bug indicates the problem
exists on an earlier kernel too. This may have been related to an update in
another package that got updated at the same time as the kernel.  The second bug
is uninteresting as it has binary only modules loaded.
