@Chistopher, thanks, the problem is now that my A15 bios can't even enter setup mode or boot anything, so I'm not sure how to try flash the most recent A16 version from (released just a month ago)? Searched the laptop's manual, and no indication of any jumpers to clear/reset NVRAM :-(
I agree and understand that firmware should be written in a way that doesn't allow the nvram boot option changes to cause it to lock up. Still, this kind of bug (even if attributed to firmware and not Linux) is occurring across at least two manufactures (Fujitsu and now Dell) whereby their 'buggy' firmware sees whatever changes ubuntu/Linux made to the NVRAM as NVRAM corruption and fail to even allow entering setup. Given changing NVRAM bios settings during an install or update (as was my case) is high risk, perhaps the install process should at least issue a warning and allow the user to opt out of of clearing and changing NVRAM settings (and potentially trigger a nasty firmware bug). I think it would in some cases be safer for a user to manually go into the BIOS setup and manage the boot options from within the BIOS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1273060 Title: [Fujitsu LIFEBOOK LH532 (UMA)] Ubuntu EFI install locks out firmware access Status in linux package in Ubuntu: Incomplete Bug description: :~$ apt-cache policy grub-efi-amd64 grub-efi-amd64: Installed: 2.00-22 Candidate: 2.00-22 EFI installation of Ubuntu clears out the boot entries in firmware leaving user with no option but boot Ubuntu. Pressing (F2) to enter BIOS Setup has no effect as does pressing (F12) for Boot Order. The only way to get back firmware access is to flash the bios using manufacturer provided utilities. Unfortunately Fujitsu doesn't provide a BIOS flash utility for Linux/Ubuntu. It is to be noted that installed Windows in EFI mode on the same system does not clear out firmware access but just adds the 'Windows Boot Loader' entry at the top of the boot sequence.
