Hi Bharat
Thanks for the reply. I have observed following thing
If IOMMU is enabled in BIOS and I use following option FCH SATA Debug Options --> Unused SATA Port Auto Shut Down Disabled. Issue is not happening. I have attached dmesg and lspci output with this option
Also I have attached lspci log with IOMMU disabled.
When issue is happening I am not able to take lspci logs as it stops in initramfs itself. I will try to get.
Thanks

Can you post the end sata device lscpi -xxx -vvv content.
