4.7.0-rc2

[radolfyr at web.de]

4.7.0-rc3 is much more stable, but still may messages when invoking dmesg... No hangs so far.
Under Windows there is a driver file called realtek_fw_sst.bin, which seems to be similar to fw_sst_0f28.bin-48kHz_i2s_master
Replacing the file did not work. Any ideas?
The chip seems to be the same  like in the T100TA (Realtek 5640)
ACPI\VEN_10EC&DEV_5640&SUBSYS_1179F850

After I destoryed my debian installation I now give it a new try, but this time on an USB Stick. The default debian kernel runs horrible unstable. It seems to run much worse than from the SSD. Now I will test you kernels...
best regards

Looking at this diagram
 ​
​I think there's a fundamental problem with the "Storage Hub" subsystem.

When I first tried linux on the TCM, even the internal eMMC was problematic, with timeouts on reads and writes (I was surprised I even got linux installed at all!).

 

 

Nicholas also felt at the time there were problems with the display controller, triggered by X11, which weren't seen in Android because it doesn't use X. Those problems seem to have settled down now. Or been overshadowed by other problems.

 

 

If our problems are ACPI related, where the hardware is being set up wrongly causing problems with interrupt sharing and race conditions etc.

​Since Windows runs relatively reliably, I can only assume that it overrides​ the DSDT information in order to set up the hardware correctly. I don't know enough about Windows to try and extract its "live" DSDT table, which I think is what we need?
