I just installed kernel 2.6.11 on my SuSE 9.2 box. Not because I like compiling kernels (my finger nails are short after that) but to get my new Audigy 2 Value sound card to work.
But doing that broke fglrx. I tried reinstalling 8.8.25 but got compile errors. I then tried 8.10.19. The "make modules" step completed albeit with a lot of warnings. But the "make install" failed. Couldn't find "modules_add". But after replacing "modules_add" with "modules_install" in /usr/src/kernel-modules/fglrx/Makefile then also that step completed without fatal errors. But fglrx still doesn't work. I get "DRI initialization failed!" in the X log. lsmod does not show fglrx. So I tried modprobing it. And that failed. And dmesg says "fglrx: Unknown symbol remap_page_range". I googled for remap_page_range and it appears that that function has now been removed from the kernel and that remap_pfn_range is to be used instead and that that takes a little more than just a simple name change.
But otherwise 2.6.11 works ok so far. I haven't come across any misbehaviors yet. And it is more responsive.
