I discovered the following badness while trying to install Fedora 10 Alpha on a
QS21 Blade:

Installation method: DVD

Red Hat,
Mirroring this bug for your awareness.

-thanks.
Comment 1 IBM Bug Proxy 2008-08-15 07:20:31 UTC 
This should be fixed by the patch "powerpc: Fix lockdep IRQ tracing bug" that I
send to the linuxppc-dev list today. I'm attaching it to this bug as well.

The backport to whatever kernel they have in fc10 should be trivial,
just a matter of the file irqflags.h being in a different place
(include/asm-powerpc/irqflags.h vs. arch/powerpc/include/asm/irqflags.h)
Comment 2 IBM Bug Proxy 2008-08-15 07:20:39 UTC 
Created attachment 314376 [details]
Fix lockdep irq tracing bug on powerpc

Patch is against 2.6.27-rc* with the new location for the arch includes. A
backport to .26 would look for the patched file in a different place.
Comment 3 IBM Bug Proxy 2008-09-30 14:02:50 UTC 
Fixed in Fedora 10 Beta with kernel 2.6.27-0.352.rc7.git1.fc10.ppc64 Thanks!
