On Ubuntu Bionic with the 5.4.0-1038-aws kernel the crash utility 7.2.8-1ubuntu0.18.04 fails with:
crash: cannot determine VA_BITS_ACTUAL
This bug/change in crash provides a workaround for 5.4+ https://github.com/crash-utility/crash/issues/52 kernels.
While it appears as though it this was fixed it https://bugs.launchpad.net/ubuntu/+source/crash/+bug/1858958 it still doesn't seem to work with a 5.4 kernel including. I also tested https://launchpad.net/ubuntu/+source/crash/7.2.8-1ubuntu0.18.04.1/+build/18807621/+files/crash_7.2.8-1ubuntu0.18.04.1_arm64.deb and it exhibits the same problem. |

arm64: Change tcr_el1_t1sz variable name to TCR_EL1_T1SZ
Series affected :
Kenrel :
This affects Focal (5.4 kernel) and Groovy (5.8 kernel).
Hirsute already contains the commit and kernels prior to 5.3 are not affected.
Crash :
The commit is already in Hirsute.
Groovy, Focal and Bionic are affected.
In case of Bionic the bug appears only if 5.4 hwe kernel is used.
