Start your bisect with the change right before this one: commit a2fb23af1c31ad6e0c281e56d385f803229d57fa Author: David S. Miller Date: Wed Feb 28 23:35:04 2007 -0800 [SPARC64]: Probe PCI bus using OF device tree. Almost entirely taken from the 64-bit PowerPC PCI code. This allowed to eliminate a ton of cruft from the sparc64 PCI layer. Signed-off-by: David S. Miller Unfortunately, if the tree works right before this change, you can't just add this one because a subsequent fix is needed before ultra5/ultra10 will work again, but it's this one: commit 01f94c4a6ced476ce69b895426fc29bfc48c69bd Author: David S. Miller Date: Sun Mar 4 12:53:19 2007 -0800 [SPARC64]: Fix sabre pci controllers with new probing scheme. ... So you could test these two commits: deb66c4521e119442aa266553e8cbfc86eb71232 a2fb23af1c31ad6e0c281e56d385f803229d57fa Thanks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
