Re: EFI stub: Warning: unable to unprotect memory range

Hi guys

So, given that Asrock have released a fixed version, is it known whether the fix was due to the new AGESA 1.3.0.0a or is it something Asrock themselves fixed? I recently bought an X870E Aorus Master and an X870E AORUS Elite X3D, so this couldn't be more annoying.

Thanks

Re: EFI stub: Warning: unable to unprotect memory range

The only solution for gigabyte owners like us is to pester them enough and pray they do something, I tried as mentioned before and got the usual answer.

Re: EFI stub: Warning: unable to unprotect memory range

I downgraded and no errors anywhere

Which BIOS version are you using?

Re: EFI stub: Warning: unable to unprotect memory range

I have the b850 and I'm at the F7 version but you have to use the one before the asega 1.2.8 bios unless you have a new Ryzen CPU but as far I know this problem didn't mess my system but I'm no expert I downgraded anyway because who knows

Same issue on MSI MPG B650I EDGE WIFI . Just a warning and everything runs (but I don't like it)

Re: EFI stub: Warning: unable to unprotect memory range

Btw, it is not just a warning. If you're using TSME as a means to better safeguard your disk encryption, keep in mind that this error will cause it to be disabled. SMAP (Supervisor Mode Access Prevention) is also disabled. Someone more knowledgeable than me can probably better explain why that's important, but it seems to control when code running in privileged mode can access user-space memory.

Either way, it seems like a reduction in security so I would encourage people to downgrade until AMD fixes the issue.

Re: EFI stub: Warning: unable to unprotect memory range

I tested the latest BIOS F12a on my Gigabyte X870E AORUS PRO, which comes with AGESA 1.3.0.0a, and the issue is still present. I rolled back to F9 (AGESA 1.2.0.3g)

Re: EFI stub: Warning: unable to unprotect memory range

I had have this issue on my Gigabyte X870E AORUS MASTER.   I only noticed it today and hadn't updated the BIOS since early Feb (BIOS F12).

Updated to F13a today and the message still appeared

Internet search brought me to this thread and also this from the linux mint forums https://forums.linuxmint.com/viewtopic.php?t=436503.   It referenced an askubuntu thread (https://askubuntu.com/questions/1519290 … 39#1528839) which suggested turning on secure boot, resetting keys to default, and then turning off secure boot.

EDIT:  Spoke too soon,  message came back after a couple of reboots

This worked for me.

Steps from the linked posts are below:

1. Boot into your computer's BIOS settings. (Repeatedly pressing the delete key during reboot is the most common way to get into the BIOS.) In the BIOS go to the Security tab. (in my case it was the "boot" tab in the gigabyte BIOS.)

2. Enable Secure Boot. Change Secure Boot from Standard to Custom. This creates a new menu to configure Secure Boot.

3. In this new menu it lists Secure Boot keys. There should be a reset to defaults option. Select it to reset your Secure Boot keys.

4. Leave the custom menu and turn Secure Boot back into Standard mode, then disable Secure Boot. (Most, maybe all, Linux distros do not support Secure Boot.)

The only solution for gigabyte owners like us is to pester them enough them and pray they do something I tried as mentioned before and got the usual answer.

I think pestering worked, as I was sent a patched BIOS after messaging them (B650 Gaming X AX). The issue is now gone for me, hopefully they'll deploy it globally soon.

Thanks for the update I will try the fix when they release it

You're having better luck than I am. So far I've been told:

1. I must delete all my partitions and format my "primary C drive"
2. I have to reinstall Arch
3. I can rollback to version F10 if I want to
4. They won't release a new version with the old AGESA code (wut?)

I'm not sure which one is more ridiculous... and all in response to a bug that has been reported to several manufacturers multiple times over the last 4 months? After so many disappointments with Gigabyte, this feels like the last straw. These are probably the last boards I buy from them.

Re: EFI stub: Warning: unable to unprotect memory range

well - the real issue about many oem just refuse linux is simple captialism: money - or more precise: thier greed for get most of it as pure clean profit
for windows they have have to support the current one plus one or two earlier versions - and of windows there's exactly one flavor: M$ windows
this reduces cost to be spent not just on developement and test but also on support

for consumer hardware this is true not just for the mainboard oem but also for amd, intel and nvidia

as consumers our power is our money: if you're unsatisfied with some manufacturer don't show them by ranting about them - show them by no longer throw money down thier throat - and spread this as wide as possible

F13b?  I only have F12b available (https://www.gigabyte.com/Motherboard/X8 … pport-Bios), and the issue still persists.

Re: EFI stub: Warning: unable to unprotect memory range

Two new AGESA 1.3.0.0 updates ... from March. The older one is labeled a beta. The new one mentions something about "anti-cheat". Last time I asked MSI support, they said they don't support Linux.
