But I've got something even better for you all, got a BUG from something tcp-related. Mind you, I am trying to find a possibly hardware-related issue here, so if this bug does not make any sense it might be my hardware! I would actually want to know it if this is likely hardware-related or not, since I have no idea if its RAM, CPU, motherboard or "only" a disk that is broken. I know _something_ is broken, due to lockups, and seeing a faulty disk indicated in a HDD diag, but only once, the disk is apparently fine 99% of the time. --- John Bäckstrand [148475.651000] ------------[ cut here ]------------ [148475.651050] kernel BUG at net/ipv4/tcp_output.c:918!
