description |
Some SSD drives made by LiteOn can crash the kernel due to bad drivers. 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.

Signed-off-by: Xinyu Lin <xinyu0123@gmail.com>
Signed-off-by: Tejun Heo <tj@kernel.org>
Cc: stable@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) |
== SRU Justification ==
Some SSD drives made by LiteOn can crash the kernel due to bad drivers. This is a
regression introduced by commit e0edc8c54646. This regression is fixed by mainline
commit db5ff909798, which was added to mailine in v4.15-rc9.
This commit has already been added to Bionic via upstream stable udpates. Xenial
also needs this fix because it recieved the regression introducing commit e0edc8c54646
via the 4.4.48 stable updates(See bug lp1663657).
== Fix ==
commit db5ff909798ef0099004ad50a0ff5fde92426fd1
Author: Xinyu Lin <xinyu0123@gmail.com>
Date: Sun Dec 17 20:13:39 2017 +0800
libata: apply MAX_SEC_1024 to all LITEON EP1 series devices
== Regression Potential ==
Low. This commit was also cc'd to upstream stable to fix a regression, so it
received extra upstream review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
