crash: read error: kernel virtual address: 1020009d024 type:
"tss_struct ist array"
Not sure how to read this.
When the vmcore is created by "snap", it first looks at /proc/iomem for
the regions of physical memory that are dumpable. Therefore it rejected
any physical address above f7feffff, which is the problem at hand.
f7ff0000-f7ffefff : ACPI Tables
f7fff000-f7ffffff : ACPI Non-volatile Storage
Just for sanity's sake, what does "cat /proc/iomem" show?
