I don't think it's harmless. My Ultra5 has an add-on PCI USB controller card (Belkin). A 2.6.18-rc kernel compiled with gcc-4.1.1 will throw a few unaligned accesses when I initialise USB by inserting a USB memory stick. Removing the memory stick then results in PCI errors and other breakage. The same kernel compiled with gcc-3.4.6 has no problems at all, so I've been assuming it's a gcc-4 issue and not a kernel issue. /Mikael - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
