Well, it could be something completely different ;-) This crash happens when Sphinx/python finds a character it doesn't recognize as valid, like if you run something like: $ echo -en "What:\tBROKEN description\ndescription:\n";dd if=/dev/random count=10 ) > Documentation/ABI/testing/foobar $ ./scripts/get_abi.pl rest 2>/dev/null|grep BROK Binary file (standard input) matches On such case, non UTF-8 chars end being inserted, causing python and/or Sphinx exceptions, causing it to crash: WARNING: The kernel documentation build process support for Sphinx v3.0 and above is brand new. Be prepared for possible issues in the generated output. enabling CJK for LaTeX builder Sphinx parallel build error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa8 in position 1985806: invalid start byte make[1]: *** [Documentation/Makefile:91: htmldocs] Error 2 make: *** [Makefile:1790: htmldocs] Error 2 Yet, this sounds a weird to me: UnicodeEncodeError: 'latin-1' It sounds that it is somehow trying to use latin-1 alphabet, instead of utf-8. This will certainly cause troubles, as there are non-latin-1 characters at the docs (specially at Japanese and Chinese translations, but there are also a few utf-8 graphic symbols somewhere else). I remember there were a change in the past that made utf-8 to be default for Sphinx, but can't remember the details. Thanks, Mauro
