As per the title. I wrote the fuse value of 0xfe which disables the reset pin on this MCU. I then put 12V on the reset pin, and tried to write the value 0xff, which should enable it again. AVR dude says the value was written, but then spits out this:

There are 0 votes so far. Votes easily highlight which items people would like to see resolved in priority, independently of the priority of the item set by tracker managers.
The flush is not correctly stitched.
Maybe this is of course also the compiler is to blame. And on fuse addition, despite the fact that it was stitched 0xFE activated WDT and does not turn off .... only #asm (wdr) helps.
