This happens only in the following combinations:
1. smartpqi is built as module, not built-in;
2. We have a disk connected to smartpqi card;
3. Both kexec's 1st and 2nd kernels use this disk as Rootfs' mount point.
This issue can be found on my ARM64 board: QDF2400:
kexec -l
On my HXT Semiconductor REP-2 board, I can use a LTP case "read_all"
to reproduce it as below:
/opt/ltp/runltp -f fs -s read_all_sys
or
read_all -d /sys -q -r 10
Or just simply visit the sys node "QCOM8002's pinconf-groups":
"cat /sys/kernel/debug/pinctrl/QCOM8002\:00/pinconf-groups"
