It used to be that fatfs would hit the second BUG() in fat_get_block() when a file reaches two gig. But I can't make that happen in testing, because the s_maxbytes stuff restricts it to 2gig-1. What you *should* have seen was `wget' locking up because of a different bug :) Are you sure you got this with 2.4.4? If so, please run the output through ksymoops -m System.map < oops-text
