Been experimenting with CentOS 5.4 some more. In order to get my wireless card to work (Broadcom BCM4311) I need Broadcom's wl.ko driver (http:// www.broadcom.com/support/802.11/linux_sta.php). It compiles fine after the necessary modification in typedef.h, loads and wireless works. However, as soon as I put some load on that interface (scp something from another machine, download something with Firefox, etc.) the machine kernel panics. I've tried the stock 2.6.18 kernel, the latest 2.6.18-164-11, and the latest patched 2.6.18-164-11-bug4139.4192.4196 (necessary to get my ALPS touchpad to work). I've tried two different versions of Broadcom's driver: 5.10.79.10 and 5.60.48.36. It doesn't kernel panic when I unload the wl kernel module, plug in a network cable and copy those files over ethernet.
I downloaded the 2.6.27 kernel source and compiled my own kernel and it seems to work with that. However, for some weird reason, with any given self-compiled kernel (tried 2.6.18-8, 2.6.25 and 2.6.27) klaptop won't allow me to configure any standby/hibernation options because it doesn't recognize any of them. They do work perfectly fine though, I can pm- suspend the laptop from command-line.
Any idea what else I could do? Either getting wl.ko to work with 2.6.18 (does somebody have a version older than 5.10.79.10 that they could email me?) or getting klaptop to realize that the laptop does indeed know how th suspend and hibernate with a non-CentOS-kernel would be fine.
Thanks, Martin

There is a "CentOS" kernel 2.6.24. If you wish to give it a try, you can download from my site at:
http://centos.toracat.org/kernel/centos5/realtime/
It is a direct rebuild of the Red Hat MRG realtime kernel[1]. Please note that I offer them for testing purposes, not for production use.

Thanks Akemi, suspend and hibernate seem to work with your kernel. Funnily enough it's only KDE3 that doesn't accept my self-compiled kernels. With Gnome I can suspend and hibernate from the System menu while KDE3 doesn't offer me any option to do so. This means there must be something compiled into these kernels, or some option ticked or not ticked, that makes KDE3 realize it's capable of suspending and hibernating.
I'll try the wireless module next. Could you tell me what exactly is different about a realtime kernel compared to a non-realtime kernel? Is it just the scheduling?
Thanks, Martin

I think that the best source of information is at the MRG web site:

Bad news. Just like my self-compiled 2.6.25 and 2.6.27 kernels my laptop froze with your kernel and the wl.ko module, too. It didn't kernel panic and it lasted significantly longer than with 2.6.18 but it still froze in the end.
I'm back to 2.6.18-164-11-bug4139.4192.4196 now. Instead of Broadcom's proprietary wl.ko module I'm now using bcm43xx with an extracted Broadcom firmware that I extracted via b43-fwcutter. That one has been running perfectly fine for the entire day now without freezing, crashing, or anything. And both standby and hibernation seem to work just fine.

I just wanted to let you know (in case you are not aware) that the kernel 2.6.18-164-11-bug4139.4192.4196 is a test base for the centosplus kernel. When the next kernel update comes out, it will be "promoted" to the official cplus kernel. If you would like to continue using this kernel, please be sure to configure your .repo appropriately ( http://wiki.centos.org/AdditionalResources/Repositories/CentOSPlus ).

Thank you, I was aware of that and have already configured my repos accordingly. I may, however, move to a newer kernel once I figure out why KDE won't recognize any standby or hibernation capabilities with newer kernels.

you can try rpmfusion.org given rpms or source rpms i had problems with my wifi (bcm4328) on fedora12, and best sollution I got is to use rpmfusion rpm's if I remember I installed broadcom-wl, kmod-wl-5.10.91.9.3-3.fc12.6.i586 and kmod-wl-5.10.91.9.3-3.fc12.6.i586 rpms and wifi worked just fine

As far as I know, the EL5 repository of RPMFusion does not provide the kmod-wl (I'll be happy to be proved wrong!)
