I have two of variant 0.

rbert:
Mine is variant 0, too.

Thank you very much, it works.
Now I can test lower voltages.

EDIT:
no problems with 0x80 | 20
I can now confirm, that my fuzev2 variant0 works like a charm with
- Patch Set 7 471ced2d0f1df1f6e53824197c93e52563fdac3a
- rockbox-restore_irq.patch.txt
- the same changes in firmware/export/config/sansafuzev2.h as in the other config files

EDIT2:

My daughter just got an ' Undefined instruction set ...' crash with this build.

I have NOT found any issue with this build on MY fuze (and have not heard any further report from my daughter). So I would say it's pretty good.

Could you charge the battery and then do a battery bench?
