The kernel crashes after booting when running services. With the linaro toolchain, the same happens but when I reboot the system. It is hard to see a clear error, as randomly the console shows an infinite dump, a couple of lines saying "Invalid address". I have been asking Vincent to test if its board was crashing and it appears the same happens. After git bisecting, I found this commit is the offending one. c2febafc67734a62196c1b9dfba926412d4077ba is the first bad commit commit c2febafc67734a62196c1b9dfba926412d4077ba Author: Kirill A. Shutemov Date: Thu Mar 9 17:24:07 2017 +0300 mm: convert generic code to 5-level paging Convert all non-architecture-specific code to 5-level paging. It's mostly mechanical adding handling one more page table level in places where we deal with pud_t. Signed-off-by: Kirill A.
