I've been working on a 2.6.19 update for FC6 over the last
few weeks, and it's starting to feel 'almost ready'.
Before I push this out to updates-testing though, I'd rather
have a few people 'kick the tyres' to make sure there's
nothing really silly wrong with these.
There are still 1-2 bits that need some more tweaking/fixing that I
already know about, but I'm blocking on other people to get those fixed.
You can find them at http://people.redhat.com/davej/kernels/Fedora/FC6/
- The big difference here vs the 2.6.19 that briefly showed up
in rawhide is that this kernel sticks with the older IDE code
(so you won't get a nasty surprise when your /dev/hda becomes sda etc).
I just don't feel comfortable pushing that as an update without
worrying about regressions.
- Another notable change in this update:
The addition of -debug kernels. All the slowdowns and nasty dmesg-filling
debug output you've come to expect in a rawhide kernel, but in FC6!
Well, hopefully not too many of the nasty messages, but this is the
same as the other FC6 kernels, but with lockdep, slab debug etc turned on
which should prove to be useful for tracking down some of the nastier
bugs we've had in recent times. The slow-down from these kernels
isn't really *that* bad on most workloads, I tend to run with these turned
on all the time, and don't notice the difference (but Santa sometimes brings
me shinier computers than others so this may not be universally true).
- 2.6.19-1.2888 and above are based on 126.96.36.199rc1 so have the fix for
the nasty data corruption bug that turned up in some workloads.
So, it's there, have it at, beat it up etc. It *should* be pretty solid,
All being well, the current plan is to get a slightly improved version
of this into updates-testing on Wednesday. I'll do an FC5 version
on the flight to LCA and will get that built and pushed to fc5-updates-testing
as soon as I get network connectivity in the land of wallabies, cork hats
