That's nothing to do with this issue. With this issue, a correct structure in a typedef or a struct with correct alignment padding turns to crap because the structure pointed to is not on a u32 boundary for example. > What kernel are you using?

Or are they generally harmless? I ask because They're not harmless if you don't fix them up and you're going to use the misaligned data for something: the data is corrupted. If you read the data and didn't do anything important with it then you won't see any problem. What gcc did you cook your kernel with? -Andy _______________________________________________ arm mailing list arm@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/arm
