megaraid_sas constantly reports errors

[Dag Stenstad]

I constantly (the following messages in the kernel log:

[292669.990809] megasas: Failed to copy out to user sense data
[292669.996343] megasas: Failed to copy out to user sense data
[292670.002666] megasas: Failed to copy out to user sense data
[292670.007732] megasas: Failed to copy out to user sense data

This seems to be a know bug, with a patch:

https://bugzilla.kernel.org/show_bug.cgi?id=15001

I do not know if this affects the stability of the system, as it is not under heavy load.

Hi Dag,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Same problem with dell server PE1950 but with all my dell server (PEX950 and RXXX).

I have tested the kernel linux-image-2.6.33-02063304-generic_2.6.33-02063304 and this new kernel seems solve the problem.

Hi,

The kernel 2.6.33-02063304-generic #02063304 solve the problem, no error message in two days.
Can you update the bug ?

Dag Stenstad, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest server release of Ubuntu? ISO images are available from http://releases.ubuntu.com/saucy/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
