Duplicate kernel-headers after upgrading to 2.6.35
by Ryad Ben-El-Kezadri 15 Oct '10

15 Oct '10

Hello everybody, I installed fc13 (Goddard 2.6.33 kernel). But I needed kernel 2.6.35 so I downloaded kernel-2.6.35.6-43.fc14.src on koji.fedoraproject.org followed the instructions on http://fedoraproject.org/wiki/Docs/CustomKerneland managed to make it works. However now when I run yum, I get the following warning "kernel-headers-2.6.35.6-43.fc13.i686 is a duplicate with kernel-headers-2.6.33.3-85.fc13.i686" I guess this is because the installation process ( http://fedoraproject.org/wiki/Docs/CustomKernel)<http://fedoraproject.org/wiki/Docs/CustomKernel> asked to download kernel-headers-2.6.35.6-43.fc13.i686. I will have to compile applications in userland that needs the new headers. Can I safely remove the old headers? Thanks Ryad

I'll ask Peter about the input stuff, but I suspect that's close between F-14 and rawhide as well, so it's probably a legitimate bug in 2.6.36... --Kyle > > R.

Broadcom brcm80211 driver
by Jon Masters 12 Oct '10

12 Oct '10

Folks, I've been testing out the newly Open Sourced Broadcom driver that's in the staging-next tree. Seems reliable, aside from suspend/resume (I posted one patch for handling radio is disabled on init hard crash). Sure, it'll hopefully land in staging and be in the rawhide kernel in due course, but given that I'm lazy and bought the netbook in question specifically to run rawhide(!), would there be huge objections to a patch sooner that pulled in this driver until it's there officially? Sure, it's experimental, but it's self-contained and this is rawhide. Let me know if this would be just a silly/bad idea. Jon.
