Because this problem doesn't happen at boot-time, the "bad IO" issue seems to happen only after some real filesystem work (ie the "unzip a 140MB file" etc). In one of the logs, the SATA driver issue ended up happening four hours after boot (but I think Werner could trigger it in minutes by doing heavy FS work). That's why I'd suspect some subtle race or other and/or memory allocation re-use. The subject line "boot crashs" is misleading, because that's the unrelated logfs thing that I have a tentative patch for. That said, I don't really see why ELAN would be so special. Werner: can you test without X86_EXTENDED_PLATFORM, but then picking the i486 config instead? That should approximate the ELAN configuration pretty closely, at least in things like compiler flags..
