Comment 23 for bug 1237519

The efibootmgr problems mentioned above are most likely resolved already. In 13.04, there was a kernel bug where the kernel would sometimes fail to update EFI vars. I think that's partly what we were hitting here. Here's the bug, and the issue has since been fixed:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173423

If I boot to the SATA drive, update the kernel to the latest 13.04 one, add in the updated iomemory-vsl driver for that kernel and then try to add an efi entry for the fioa device via efibootmgr, it at least succeeds:

efibootmgr -c -w -L FusionIO -d /dev/fioa1 -p 1 -l 'EFI\ubuntu\grubx64.efi'

...but, I'm not sure if what's added is entirely correct (see attached output from efibootmgr -v)

At this point, it is indeed now every important that we test things with the latest releases, given the issue I just hit here.

Brandon at FusionIO is working with his build team to see what can be done about getting a kernel module built that will work on 13.10 and higher releases. If we can get that, it'll hopefully help shake out some things that may have already been addressed.
