Instead of the warnings occurring only at the end of the mkfs runs, they now occur pretty much constantly, and it finally ends with an Bug_On. Attached is the console output. There are 20 occurrances of Badness in as-iosched.c line 1020. There is one occurrance of Badness in as-iosched.c line 1025. The Bug_On() is in as-iosched.c line 1243.
