You seem to be pretty much able to reproduce this at will, right? I'd really like to see the raw System.map and dmesg output if your syslogd doesn't do a proper job of getting the symbols interpreted: just send the things by email, and I'll put something together. It's too hard to interpret your half-way decoded thing, and I really want to see what this xmms thing is doing.. >xmms D CACC5EA8 4116 713 155 715 (NOTLB) 1493 674 >Call Trace: [] [] [] [] [] >[] [] > [] [] [] [] [] > >c01248e4 T ___wait_on_page >c0124984 t __lock_page > >c01240dc t truncate_list_pages >c0124268 T truncate_inode_pages >c01242d4 t writeout_one_page This is the smoking gun here, I bet, but I'd like to make sure I see the whole thing. I don't see _why_ we'd have deadlocked on __wait_on_page(), but I think this is the thread that hangs on to the mm semaphore.
