I double-checked, and of course you are right - the issues resurfaced after some more use, even with the patch reverted. I've written some scripts that do some compiles from scratch, and suspend/resume several times. Plan to try bi-secting with that and see what that will come up with. OTOH, from the discussion it seems just randomly pointing a finger at a patch has uncovered some bugs - so maybe we should do this a bit more :) -- MST - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
