Any v2.6.27-urgency of this patch? hm, -tip testing has found that this patch causes a hard hang during bootup: initcall ali_init+0x0/0x1b returned 0 after 3 msecs calling amd_init+0x0/0x1b bus: 'pci': add driver pata_amd bus: 'pci': driver_probe_device: matched device 0000:00:06.0 with driver pata_amd bus: 'pci': really_probe: probing driver pata_amd with device 0000:00:06.0 pata_amd 0000:00:06.0: version 0.3.10 pata_amd 0000:00:06.0: setting latency timer to 64 [hard hang] should have continued with: scsi0 : pata_amd device: 'host0': device_add device: 'host0': device_add scsi1 : pata_amd [... etc. ... ] on an AMD X2 testsystem. (Asus board) Can send more info on request. Config is: http://redhat.com/~mingo/misc/config-Fri_Aug_15_18_30_56_CEST_2008.bad Any idea why that is so? Apparently the alignment change wasnt as benign as assumed.
