The following error is due to SATA drive format failing with arm64 64k-page
size ( CONFIG_ARM64_64K_PAGES=y ) kernel.
while running LTP syscalls test suite on running 5.13.3 and 5.13.5-rc1 kernel.

First it was noticed on the stable-rc 5.13.3-rc2 kernel.

Whereas 64bit kernel and 32bit kernel pass with 4K page size.

Initially, I thought it could be a Hard drive fault but it is reproducible on
other devices but not always. Which is a blocker to bisect the problem.

The steps to reproduce:
- Boot arm64 juno device with 64k page stable-rc 5.13 kernel Image [1]
- CONFIG_ARM64_64K_PAGES=y
- format connected SATA drives and mount /scratch
- Use the mounted /scratch for LTP runs to create and delete files from this
- cd /opt/ltp
- ./runltp -d /scratch -f syscalls
