I have solved the freeze issue on my asus t200ta.
This is the "Device" section in my xorg.conf:
Section "Device"
Identifier "device1"
VendorName "Intel Corporation"
BoardName "Intel 810 and later"
Driver "intel"
Option "DPMS"
Option "TearFree" "true"
Option "AccelMethod" "sna"
EndSection
I have also added the following parameters
i915.semaphores=1 intel_pstate=disable
to boot parameters.
On my system, the kernel version is 4.1.9.
I hope that these informations can be useful to you in order to solve the freeze issue.

Nah, still nothing. And I think X11 get more freezes than I use it without xorg.conf.
Maybe it 4.2.5 kernel issue, I dunno.

The problem with Bay Trail-T is discussed at https://bugs.freedesktop.org/show_bug.cgi?id=88012
I had the freezes on 4.2 and 4.3 kernels, did not test on 3.16+ versions though.
According to the last post on 2015-11-30, I used intel_idle.max_cstate=1 kernel parameter and did not see any freezes since when.
My xorg.conf is same as the one superdinotux posted.
Hardware accelerated video decoding works fine in mplayer-vaapi, vlc is much slower.
I use cinnamon desktop environment which runs smoothly also.

UPD2: WARNING!!1 Wi-Fi antenna is overheats when using Linux and working Wi-Fi. And it heats a lot.
I know what I'm talking about - I've disassembled the tablet and know where the wifi antenna is located.There is choices:
1) Don't do this Wi-Fi working.
2) "blacklist brcmfmac" to /etc/modprobe.d/brcmfmac.conf for better time (don't forget about "mkinitcpio -P").
3) Wait for good Linux kernel or Broadcom firmware update.
P.S. On linux-baytrail kernel from AUR, overheat is still stay.Maybe I only have this overheat. Try that yourself.
That's because wlan0 has "Tx-Power=1496 dBm" by default.
I fixed it easily with "sudo iwconfig wlan0 txpower 18dBm" command.

And Wi-Fi works good?
UPD: Yeah, it works. I think "iwconfig wlan0 txpower auto" is better. In 1dBm Wi-Fi is still work good.
Guys! Has anyone tested suspend or hibernate on the tablet? It works?

Switching to "txpower auto" seams to change txpower parameter to 1dBm automatically, but wifi works.
I'm not sure how warm is the antenna, because I see no reason to dismantle the device.
I tested the hibernation and it does work, although after resuming, the wifi interface was lost, the audio stopped working as well.
Concerning the suspend mode, I was not able to do it, there is no option in shutdown menu.
The upower response for the dbus command was that kernel does not support suspend and "pmi capabilities" shows only hibernate.
I did tests on 4.3 and 4.2.6 kernels because it is the only ones which have wifi&sound working for me.

4.2.5 also have Wi-Fi support after NVRAM "cat" command.
Yes, only hibernation works good, after that Wi-Fi isn't working. Suspend turns device into a deep sleep, which have only one way out - hard shutdown by pressing power button. Before that I kill my tablet, then I was booted in Archiso. Today I have installed system and suspend not kill my device.
Sorry for bad language.

Hi,
I solve my probleme about touchscreem detectection. ( i use it to solve but it's not clean solution)
i remove the module
sudo modprobe -r i2c-hid
# and i recharge it
sudo modprobe -a i2c-hid
# after that the kernel load
# hid_multitouch and add /dev/input/event9 and tactile work if this solution work say it to me? thanx have a nice day

What's interesting, I am able to suspend. Only many things break after the wakeup. See kernel bugzilla #102611, #104201.
All my experience is just the same with kernel 4.1.2, 4.1.6, 4.3 and 4.4-rc7

Is there any way to measure this without disassembling the device?

You mean that it's not detected after a suspend?

Maybe correct suspend & hibernation support comes with properly configured and compiled kernel.
Can I see your kernel command-line?
Wi-Fi can be fixed by this command:
That's because wlan0 has "Tx-Power=1496 dBm" by default.
I fixed it easily with "sudo iwconfig wlan0 txpower 18dBm" command.
I dunno how to make this changes doing always at booting.

Oh, I was pretty sure I posted that.
I just recalled that T200TA runs Android too. Maybe we could use libhybris to get better driver support?

From my experience, the hard freezes happen only when running on battery power. Some voltage drops?
Or maybe not: https://www.phoronix.com/scan.php?page= … Trail-Fail
And my kernel command line:

If you want to avoid freezes, pass intel_idle.max_cstate=1 to the kernel command line: https://bugzilla.kernel.org/show_bug.cgi?id=109051

I've got a working wi-fi on 4.2.5 kernel and linux-firmware from official repo.
Instead of this command:
cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txtI enter this command:
cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcmfmac43340-sdio.txtI don't know where is the difference, but now wi-fi is working - interface is visible AND Internet finally works. Without any downloaded patches and firmware files.
UPD: After that you need to reload module:
rmmod brcmfmac modprobe brcmfmacor reboot.

No idea. But Wi-Fi will still work.

Same here, I've got a lot of those errors however Wi-Fi still works like a charm.

Good news, everyone. Seems like with linux-git 4.12.rc5 kernel our T200TA now have ability to sleep and hibernate himself. I tested these methods many times and one thing, which isn't working after wake up - Wi-Fi. I think it's a solvable problem by configs or something...

It's 4.14rc7 and we've got touchpad configuration and some gestures!
