Fedora Core 6 common issues
The Fedora developers have put up a page describing
common issues which have come up with Fedora Core 6, along with
workarounds. It is refreshingly short. Definitely worth a look before
installing FC6 or asking questions about problems.

Fedora Core 6 common issues Posted Oct 30, 2006 14:27 UTC (Mon) by liljencrantz (subscriber, #28458) [Link] As is the case with all short bug lists, it's only short because it's incomplete. ;-)
Fedora Core 6 common issues Posted Oct 30, 2006 14:57 UTC (Mon) by sbergman27 (subscriber, #10767) [Link] They miss the one about USB cold plug not working.
It seems like I waited forever for hot plug to work reliably.
Hot plug started working well in FC5. But now, in FC6, cold plug is broken. Boot a machine with a usb drive attached and it fails to load usb-storage and the drive won't mount.
I wish RedHat would allocate funds or donate a USB drive that the Fedora guys could use for testing.
Fedora Core 6 common issues Posted Oct 30, 2006 15:25 UTC (Mon) by thebluesgnr (guest, #37963) [Link] Maybe the problem is specific to a certain USB device? Or the controller on your motherboard? Or both combined?
Red Hat doesn't have the resources to test all the combinations of ppc/i386/x86_64 hardware possible. Instead, they rely on people like you to report bugs when they occur.
Fedora Core 6 common issues Posted Oct 30, 2006 15:35 UTC (Mon) by sbergman27 (subscriber, #10767) [Link] It has already been reported... over two months ago. And no, it is not specific to a particlar device. It can be reproduced with any drive.
I stopped bothering to report bugs to Fedora's bugzilla since my reports were often ignored, passed upstream because the person it was assigned to didn't have time to worry about it, or declared not important enough to worry about, or had a fix implemented... in FCx+1.
I do report bugs to distros whose devs act like they care, though.
Fedora Core 6 common issues Posted Oct 30, 2006 22:33 UTC (Mon) by proski (subscriber, #104) [Link] They didn't miss it. It's number four in "Less Common Issues".
Fedora Core 6 common issues Posted Oct 31, 2006 1:01 UTC (Tue) by sbergman27 (subscriber, #10767) [Link] I see. They are pointing to the correct bug number. But why is it being described as "on certain models" when all usb storage devices are affected?
Fedora Core 6 common issues Posted Oct 31, 2006 4:31 UTC (Tue) by Pc5Y9sbv (guest, #41328) [Link] It may well be certain USB controllers or system BIOS combinations that put the USB storage into a funny state before the kernel inherits them?
I've never seen "cold plugging" of USB drives work in my thinkpad, in the one case where I cared: having the BIOS load GRUB from the USB drive and having GRUB load the kernel+initrd from USB worked, but then I had to quickly disconnect and reinsert the USB cable or the kernel+initrd would not find the same USB drive to mount the / filesystem.
On the other hand, I've never had any problem with hot plugging of USB drives on my thinkpads.
There was one unfortunate period of time when it seemed I had to build the kernel with either an option to support my USB flash stick in some "slow" compatibility mode, or use a USB-ATA bridged drive at high speed. I think that is resolved, but frankly am not sure since I do not have occasion to use USB flash storage anymore.
Fedora Core 6 common issues Posted Oct 31, 2006 4:48 UTC (Tue) by mitchskin (subscriber, #32405) [Link] This fedora-devel post may have something to do with this problem.It sounds like they have a kernel patch they're trying to get upstream.
Fedora Core 6 common issues Posted Oct 30, 2006 15:35 UTC (Mon) by markhb (guest, #1003) [Link] Bug 211941 (which bit me Saturday night) is, to my mind at least, obnoxious enough to warrant a paper-bag release of CD ISO #1. After the comments about "no more separate SMP and uni kernels; we'll enable the proper bits when we set you up", picking the wrong kernel for the architecture at install time is just wrong, even if it does mainly hit those of us who choose to use binary-only drivers.
Fedora Core 6 common issues Posted Oct 30, 2006 22:28 UTC (Mon) by proski (subscriber, #104) [Link] I'm not using any binary-only drivers, yet I ended up with i586 kernels on Pentium III laptops.And the bug with static IP is pretty bad too. It doesn't affect iSCSI only - it's sufficient to select "extras" in the package list after having selected a static IP. Adding a test to the test matrix is not enough. In my opinion, all Python code should be checked for unresolved functions. I was hit by this bug with FC6-test3, and I feel bad that I didn't report it in time :( I hope we'll see Fedora Unity respins soon.
Fedora Core 6 common issues Posted Oct 31, 2006 12:06 UTC (Tue) by tialaramex (subscriber, #21167) [Link] Everybody with particular types of i686 compatible hardware gets the i586 kernel, but the most serious _consequences_ are for those who have proprietary drivers, since the drivers will build against the wrong kernel image and don't work.
Another common effect is the lack of CPU-specific frequency scaling (on e.g. my Z60m) as listed in the article. This makes your laptop run hotter and reduces battery life until you switch to the correct kernel package.
It's particularly unfortunate because similar (identical?) bugs had been reported in earlier pre-releases, so this deserved better testing. However since it's not a fatal error (you get a working install from which you can fix it safely with one or two commands) I doubt there's any special reason for a re-spin.
Fedora Core 6 common issues Posted Oct 31, 2006 13:13 UTC (Tue) by proski (subscriber, #104) [Link] However, this problem is not fixable by "yum update" unless yum is changed to check the CPU and to load the best package for the given CPU even if the package has a different sub-architecture. Such behavior is not risk free in general, and it's possible that yum will need to be "hinted" or rather "hacked" for this specific problem with the kernel. Still, I'm not sure that anything like that will be done.
