After updating BIOS from "BIOS Q71 Ver. 01.15.00 12/28/2020" to version "BIOS Q71 Ver. 01.16.00 04/22/2021" most of the memory got unavailable in Linux. The system has 16 GiB of memory, but now free -h shows only total of 1.5 GiB. In Windows all memory seems available. No other indication of the problem in /proc/meminfo and /proc/iomem (will attach) is shown except that the total memory is 1.5 GiB. No large area is shown as reserved in /proc/iomem. But there is now an error message in dmesg that didn't use to be there: "kernel: efi: memattr: Failed to map EFI Memory Attributes table @ 0x72f69018". Also that EFI MEMATTR address seems to have changed after the BIOS update. I will also attach an earlier dmesg prior to update and a one after the update, since I updated the BIOS two weeks ago, and after that the kernel has also got updated.
