There is long standing open bug report on Mandriva which is currently beieved to have root cause in file system corruption. It shows itself in RPM DB corruption (at least, there is no other known method to trigger it). So far all reported cases happened on filesystem with 1K block size and stopped when RPM DB was moved to FS with 4K block size. There are also similar RH reports as well. Here are references: https://qa.mandriva.com/show_bug.cgi?id=32547 This one is rather long. Interesting bits are probably around https://qa.mandriva.com/show_bug.cgi?id=32547#c177 https://qa.mandriva.com/show_bug.cgi?id=32547#c148 (many users reporting dumpe2fs) https://bugzilla.redhat.com/show_bug.cgi?id=230362 https://bugzilla.redhat.com/show_bug.cgi?id=375931 https://bugzilla.redhat.com/show_bug.cgi?id=305301 The Mandriva bugzilla also mentions this mail from Stephen Tweedie http://lkml.org/lkml/2007/9/18/232 which indicates some issues with 1K blocks, but according to last comment: https://qa.mandriva.com/show_bug.cgi?id=32547#c300 it is still present in 2.6.27 (at least was present on -rc6) There was a kernel bug report http://bugzilla.kernel.org/show_bug.cgi?id=11564, but in this case it was identified as hardware issue.
