Please try this patch: https://lore.kernel.org/linux-ide/20250221015422.20687-2-cassel@kernel.org/T/#u and see if it fixes your problem. Please also make sure to check that you can still write and read back what you wrote to the device (with the read data matching the written data). Kind regards, Niklas
