I think this, too. I observed a crash in a similar configuration with my Mikrotik RB532 (mips32). I just couldn't get a kernel Oops yet, because I fighted against some PCI and serial output problems on this device. http://www.linux-mips.org/archives/linux-mips/2014-05/msg00124.html http://www.linux-mips.org/archives/linux-mips/2014-05/msg00074.html May be I can get an oops on Monday.

Thanks for the hint. I thought I only need HIGHMEM for cubox-i4pro with 2 GB. Will enable it for my cubox-i2ultra.
