Description James Laska 2008-07-30 13:07:06 UTC

While booting F10 Alpha on a IBM Power5 ppc LPAR, I see the following kernel
message during boot.

This message does not appear to negatively impact the bootup, as the system
proceeds into the installer.

The kernel used is - kernel-2.6.27-0.166.rc0.git8.fc10.ppc64

Comment 2 James Laska 2008-08-06 12:23:42 UTC

No longer seeing this with F10-Alpha (kernel-2.6.27-0.166.rc0.git8.fc10.ppc64)

Comment 3 James Laska 2008-08-06 14:35:06 UTC

Please ignore comment#2 ... that was intended for another bz.

My IBM power5 systems continue to show the following while booting the installer.

Comment 4 Christopher D. Stover 2008-10-28 19:39:56 UTC

James, this should be fixed in Fedora 10 Beta with kernel 2.6.27-0.352.rc7.git1.fc10.
