Hi, Using i.MX6dl with branch master revision c3c1d2616e59ba314c6ff602b99909da632a11d5
Several crashes have occurred with this build. The kernel appears to panic due to null pointer dereference, each time the address can differ. Suspect an issue with the graphics module but not clear at this stage. Wondered if anyone else has encountered similar issues. Samples crashes from xorg log files. Unable to handle kernel paging request at virtual address ffedf135 Unable to handle kernel NULL pointer dereference at virtual address 00000003 Unable to handle kernel NULL pointer dereference at virtual address 00000017 Unable to handle kernel paging request at virtual address fffffffc Unable to handle kernel paging request at virtual address ff2518b5 Snippet from Xorg log file.
