As a related comment, the serial port is *always* ttyS0, even when it's not there, and even when both GRUB2 itself and the kernel are all configured to go to, say ttyS1 or something completely else.
I propose to modify /etc/grub.d/20_memtest86+ * Look at /sys/class/tty/ ; if there's nothing in there that's not virtual (there should be a good way to weed out the virtual devices by looking at this), skip the serial port config * AND/OR look at GRUB2/the kernel; if they're not configured for serial communication, why should you for memtest? ** Bug watch added: Debian Bug tracker #612371 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=612371 ** Also affects: memtest86+ via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=612371 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/567955 Title: grub2 always adds "memtest86 serial console" even when no serial port To manage notifications about this bug go to: https://bugs.launchpad.net/memtest86+/+bug/567955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
