Title:
Catting the SecureBoot efivar in /sys hangs

Status in Provider for Plainbox - Checkbox:
Fix Committed
Status in linux package in Ubuntu:
Incomplete

Bug description:
During testing, a machine locked up appearing to hang on the secure
boot mode test. Looking at the test logs, both of the things that use
boot_mode_test.py have triggered this issue:

miscellanea/reboot_firmware crashed
miscellanea/secure_boot_mode crashed

as this doesn't do much beyond open up a file in efivars, this is
puzzling behaviour. Need to figure out what would trigger this and
how to work around it.
