Hi,
FWIIW :
We picked up the suspect "Fixes" commit :
2020-10-01 | x86/kdump: Always reserve the low 1M when the crashkernel option is specified
In an LTS update: 5.4.68, and I do not see the issue reported in the summary : "DMA: preallocated 128 KiB GFP_KERNEL pool for atomic allocations " , when a kdump is invoked. We test kdump quite regularly on a variety of platforms.
That commit was in 5.4.69, not .68. Or am I confused here?
that is why the 5.4 FAILED email was sent.
thanks,
greg k-h
