Doesn't seem to be distro related as it happens with Arch, Ubuntu and Gentoo too. After the kernel throws a stack trace it will hang until it gets reset (imo by the watchdog) leaving me with a unclean filesystem. Switching back to the original bootscript (4.5) is impossible as it disappeared because of security issues (thats what support said).\r\n\r\nSCW support suggested to file an issue here.
