Title:
On Boot after ramdisk loads: ACPI BIOS error (bug)
AE_AML_Buffer_Limit, ... is beyond end of object
Status in linux-signed-hwe-5.19 package in Ubuntu:
Confirmed
Bug description:
this tool shows linux-signed-hwe-5.19? But Grub shows 5.19.0-32-generic
After regular Software Update to kernel 5.19.0-32-generic
on boot
after the boot disk is decrypted, and the ramdisk loads:
the error message (see attached jpg) shows briefly before continuing to load
to the log in screen. No noticeable problems, but I've not tried to suspend
(which in the past works, most of the time) with this kernel loaded.
Per wiki.ubuntu.com/Kernel/Bugs
1, hardware: see screenshot of Settings/About
2. every boot to this kernel produces the error
3. Does NOT Exist in previous kernels 5.15.0-60-generic and earlier
4. Problem: not sure how to test the latest development Ubuntu kernel version
as well as the latest upstream mainline kernel.
Towards a solution: This probably is the latest development kernel?
(I've looked at
https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds,
AND
I'm not familiar enough with the language to understand what I'd be doing, so
unless I have specific directions on how to test the latest development and
upstream mainline kernels, I'm not about to stab in the dark at it.
I only get the basic drift that this bug may be fixed in the upcoming
kernels, and installing them may or may not work (for other reasons) on the LTS
I have running now.
this command gives this result
$ cat /proc/version_signature
Ubuntu 5.19.0-32.33~22.04.1-generic 5.19.17
Not sure if this is a security risk or not, so to be safe I ticked
that it is. Smells like it to me, anyway.
