4G/4G memory split was enabled in all i686 FC2 development kernels after version .118. This has caused several problems with various kernel components that need to be individually isolated, confirmed and fixed. This is the master tracking bug for both suspected and confirmed 4G/4G problems.
Currently known problems: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=118165 Broadcom b44 network driver https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=117032 S3 sleep/resume problems https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=118205 Savage/IX-MV (MobileSavage) X-server
Please nominate bug numbers as comments within this report, and add it to the Bug dependency list after they are confirmed 4G/4G problems.
http://people.redhat.com/wtogami/temp/4G/ For your convenience I will try to maintain the latest FC2 devel i686 kernels rebuilt here with 4G/4G disabled in order to aid end-user testing. Please test both the official kernel and this rebuilt test kernel and report any differences in behavior.
If you have noticed any kernel behavior that was working in earlier FC2 2.6 kernels but broke recently, then please try the above i686 test kernel to see if it makes the problem go away.
