Megaraid_sas Driver Update Request

[Anand Lodnoor]

Please consider below megaraid_sas driver's upstream commits for upcoming UBUNTU releases:

commit 7fa3174b3ef4e517ebb8a08078871ceab705a969
7fa3174 scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout

commit 62a04f81e6133c8eaa5e93e15eab1ad2511a45db
62a04f8 scsi: megaraid_sas: IRQ poll to avoid CPU hard lockups

[Christian Ehrhardt  (paelzer)]

Changed to be a kernel bug, as this doesn't seem for bind9 (as reported right now)

[Christian Ehrhardt  (paelzer)]

Also I wonder if this should be a dup to 1838751 and better track all three changes in one bug?
But so far I keep that a suggestion for the reporter or the kernel Team

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1838755

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This is not a duplicate of BUG #1838751.

BUG #1838755 is just a request (not a BUG) to integrate the megaraid_sas driver update/changes which would handle certain scenarios identified as critical ("critical" in the sense,that, if these scenarios are not handled the driver may not function as expected).

The above issue was identified, fix is reviewed and is submitted to the upstream. Once the fix is accepted the commit id will be shared.
