I do push not because I have something against Charles but because I want it to work. I wouldn't touch it at all but my supervisors want it in our product that we had to ship day before yesterday due to lack of alternatives. > And you've just missed another huge rant, possibly obscuring what might > be a valid bug report - it's very hard to tell. Here is a different view of that bug, now from mounting it with mount (root is on NFS). It crashes at exactly the same place in yaffs_GutsInitialise(). And BTW, that was not a rant. That was just a facts constantation. I'd like you guys to read it and think it over. There are some bugs named there and their possible causes. And no, it is not a good idea to cast something like yaffs_PackedTags2 pointer to (__u8 *)... === Cut === ksymoops 2.4.11 on i686 2.6.12-1.1456_FC4smp.
