Hi. I have a ASUS Tp202NA convertible and setting the emmc speed to
HS200 just made the internal disk discoverable. I'm going to install
kubuntu 19.10 on it to see if it works and report here. Thank you all
for your help!

I tried to reproduce this problem with an ASUS L403NA with an Intel
N4200 processor and SanDisk DF4064 eMMC, but it worked fine.
For people still experiencing this issue, here is a debug patch that
will print debug information to the kernel messages to help analyze the
issue. It can be applied
Oh never mind, it also works with 5.3. I don't remember then which
kernel I actually tried, but issue seems to be fixed.

I had similar issues on Chuwi Hi13 tablet with the same eMMC module.
It looks like latest 5.4-rc3 fixed that issue for me. I haven't tried other 5.4
kernel, but tried some of older kernels and older distros and 5.3 family.
I tried 5.4-rc3 on Arch Linux and it worked all good.

Yes there is, but up the machine while preesing f8, press esc when the
boot popup shows up. Head to advanced mode then advanced and under that

Okay as a temporary solution lower the speed to hs200. Boot up the
machine while hitting the F8 button, press cancel when the boot options
box pops up. Then proceed to advanced mode(f7), here go to Chipset/South
Cluster Configuration/SCC Configuration. Here select eMMC max speed and
select hs200.
I have exactly the same bug on a newly purchased Asus VivoBook Flip 12 TP202NA.
The emmc is an SanDisk DF4032 749B806.
Lubuntu 18.04.2 installer finds for time to time the emmc but I've never
been able to boot the system successfully.
