How to solve this? Thx! 

can you do a normal hibernation without xbootmgr?

can not..

Yesterday before i sleep i try normal hibernation again. Then when i woke up in this morning, my laptop still run and didn't hibernate at all. 

 Pls tell me how to solve this.. I feel so worry.. Thx!  

create a new topic here in the win8 forums which deals about your issue. This topic is about perf issues not that hibernation fails completely.

Getting the following error when trying to generate the xml file.

 

xperf /tti -i boot_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_boot.xml -a boot

                1424825 Events were lost in this trace.  Data may be unreliable.

                This is usually caused by insufficient disk bandwidth for ETW logging.

                Please try increasing the minimum and maximum number of buffers and/or

                the buffer size.  Doubling these values would be a good first attempt.

                Please note, though, that this action increases the amount of memory

                reserved for ETW buffers, increasing memory pressure on your scenario.

                See "xperf -help start" for the associated command line options.

this happens when the disk was busy writing all data to the ETL file. Open the ETL with the viewer and look at the disk graph. If it is 100% for a longer time, replace your HDD with a SSD to fix this bottleneck.

Having problems with Windows 8.1 booting really really slowly. I've tried looking in the XML but I'm stumped. ETL link sent via PM.

the following ASUS service starts slowly:

<serviceTransition name="AsusFanControlService" group="" transition="start" totalTransitionTimeDelta="30000" firstCheckpointTimeDelta="30000" 

This causes a 30s delay.

Can u analyse my boot trace?

here he is... http://www.filedropper.com/bootbasecswitchdriverspower1

This is a strange one. I've installed Win 10 in a separate partition on my SSD and am booting between them with grub4dos using:

 

title  Win 8.1 (SSD)
unhide   (hd0,0)
hide  (hd0,1)
root  (hd0,0)
makeactive
chainloader /bootmgr

 

title  Win 10 (SSD)
unhide   (hd0,1)
hide  (hd0,0)
root  (hd0,1)
makeactive
chainloader /bootmgr

 

If I boot from cold then they boot normally (well Win 8.1 certainly did, haven't tried Win 10 yet) but if I boot one then reboot into the other (or even just rebooting Win 8.1 back to 8.1 I've found), they both get stuck on the boot screen for about 40s before the animation circle appears. I tried enabling Boot Log, OS Boot Information and No GUI Boot in msconfig but that doesn't make it show the drivers as they load like Win7 did, so I can't see if it's getting stuck at a particular driver.

 

Could you take a look at my traces please MagicAndre? I did a boot trace when it booted normally and another when it hung for 40s but looking at the xml I can't see anything obvious. The second trace overwrote the first .etl, so this zip only contains the second (slow) one and the two .xml files .https://drive.google.com/file/d/0B1fDI89phEESVmJuM0xtR3JyRE0/view?usp=sharing
