Hi All, The bug is definitely in the commit a8a217c22116eff6c120d753c9934089fb229af0. [1] The kernel 4.14.0 boots without any problems on my Varisys Cyrus Plus board [2][3] and on my Varisys Nemo board [4]. I have patched the kernel 4.14.0 source code with the bad commit I found with bisect last week. After compiling, the kernel 4.14.0 doesn't boot anymore on my Varisys Cyrus Plus board [2][3]. Please help to find the bug in the bad commit. (Bisect log attached) Thanks, Christian [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a8a217c22116eff6c120d753c9934089fb229af0 [2] http://www.amigaos.net/hardware/133/amigaone-x5000 [3] http://wiki.amiga.org/index.php?title=AmigaONE_X5000 [4] https://en.wikipedia.org/wiki/AmigaOne_X1000
