OTOH I thought when I put in some keywords from the backtrace in my query 
it might get the attention of the right people. When I just say unknown

I wouldn't do that for sensational purposes.

Maybe next time: "Fails to boot with partially shown backtrace, with some 
ext4 / readahead function calls inside it"? Or even more general some I/O 
/ filesystem related functions?
