I can reproduce it and Peter's patch does fix it for me. e.g. [EMAIL PROTECTED]:/sys/devices/system/cpu/cpu1# time echo 0 > online real 0m6.743s [EMAIL PROTECTED]:/sys/devices/system/cpu/cpu1# time echo 0 > online real 0m7.770s I've observed delays from ~3 s. up to ~8 s. (out of ~20 tests) so the 10s. delay of msleep_interruptible() might be related but I'm still looking for the reason why this fix helps (and what goes wrong with the current code). > > Ingo > -- Best regards, Dmitry Adamushko -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
