A fix for this issue has been submitted upstream: https://git.kernel.org/pub/scm/linux/kernel/git/tj/libata.git/commit/?h=for-4.15-fixes LITEON EP1 has the same timeout issues as CX1 series devices. Revert max_sectors to the value of 1024. 'e0edc8c54646 ("libata: apply MAX_SEC_1024 to all CX1-JB*-HP devices")' Signed-off-by: Xinyu Lin <xinyu0...@gmail.com> Signed-off-by: Tejun Heo <t...@kernel.org> Cc: sta...@vger.kernel.org At a high level the root cause of this problem is that the device only supports commands with a transfer size up to 512KB. This worked fine with older versions of Linux but newer versions are attempting commands with a transfer size of 1280KB which is problematic for this device (LITEON EP1-KB480) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743053/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
