Hi Abhishek,

I guess the address convention seems x8664 when looking at 0xffffffxxxxxxxx type sort of 64 bit virtual address.

------

crash: invalid kernel virtual address: fffffff791ff5a5f type: "64-bit KVADDR"

-----

For arm64 bit the addressing would more be sort of 0xCCAbxxxxxxx sorts. Due to the convention of memory addressing start addresses.

As a first check confirm if your crash and vmlinuz file is x8664 type

# file vmlinux

# file crash

Hi All,

I was wondering if there is any change required in either crash utility or
RT Linux to make use of crash utility to analyze ramdump with RT Linux.

I am using crash 7.3.0++ and Linux - 5.4.61-rt37 on arm64 target.
I see the below error:
../crash DDR0.BIN@0x80000000,DDR1.BIN@0x100000000 vmlinux
--machdep vabits_actual=39 --kaslr 0x2ff9600000
......
crash: invalid kernel virtual address: fffffff791ff5a5f type: "64-bit KVADDR"
