This bug has been fixed in Jammy, but not yet marked Fix Released apparently due to an issue with the Launchpad bot (reported to the Launchpad team); leaving as Fix Committed so to trigger when the bot runs again for it.
linux (5.15.0-83.92) jammy; urgency=medium
* kdump fails on big arm64 systems when offset is not specified (LP: #2024479)
- arm64: mm: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
- arm64: kdump: Reimplement crashkernel=X
- docs: kdump: Update the crashkernel description for arm64
- arm64: kdump: Do not allocate crash low memory if not needed
- arm64/mm: Define defer_reserve_crashkernel()
- arm64: kdump: Provide default size when crashkernel=Y, low is not specified
- arm64: kdump: Support crashkernel=X fall back to reserve region above DMA

That is also reflected in linux-hwe, see comment #37:
