Memtest86+

I installed Systemrescue from the System | Kernel page and manually edited the /etc/grub.d/42_sysresccd file to allow booting to a serial console and then ran update-grub. This all worked, but when I boot to Systemrescue in the grub boot menu I don't see the option to boot memtest86+. I could have sworn that older versions provided this. Am I missing something?

The kernel plugin has a dependency on the memtest86+ package which should install the grub menu entry. Do you have the /etc/grub.d/20_memtest86+ file?

/etc/grub.d/20_memtest86+ is missing.

I do have a 20_linux_xen file, but it seems unrelated. I reinstalled the memtest86+ package, but it didn't drop a 20_memtest86+ file.

I also reinstalled openmediavault-kernel but it didn't change anything.

No idea why reinstalling memtest86+ doesn't drop the /etc/grub.d/20_memtest86+ file. So I extracted it out of the package and dropped it in by hand. I edited it to change the serial port to ttyS1 and ran update-grub.

Able to boot into memtest86+ now but it locks up soon after starting. I seem to remember this is what happened the last time I tried this, but was never able to get it sorted out.

You did sudo apt-get install --reinstall memtest86+?

Yes, that was the command I used.

I tried this and it threw errors when removing the kernel plugin.

fred@omv:/etc/grub.d$ sudo apt-get remove --purge memtest86+

That fixes it, thanks. Still going to try to figure out why it crashes/locks up the SOL session.
