Bug Description
When rebooting after a Linux session, the UEFI and grub boots are extremely slow and the process takes 3 minutes
- As soon as the kernel boots, ie. luks input, everything is fine again
- OS X boot and option-boot is slow too, fast after FileVault password input
- Internal keyboard and touchpad is extremely slow, like 30 s per key press.
- Plug in usb keyboard and mouse: works fine, while the internals are still slow
After an OS X ession upgrading to 10.11.04, the boot got fast again
- After the net Linux session, back to slow
Impact: boot takes 3 minutes
get-around: lots of patience, possibly use of external usb keyboard
