Bug Description


Random crashes when using the bnx2x driver on power 8

[Test Case]

heavy use of the bnx2x driver on power 8

[Regression Potential]

introduces a simple memory barrier and is therefore very low risk, any such risk would normally affect performanc e not function.


---Problem Description---
bnx2x may cause crashes or stop working because of a missing memory barrier.

Messages like the following appear on the log:

bnx2x: [bnx2x_tpa_start:392(eth7)]start of bin not in stop [0]

---uname output---
Linux ubuntu 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:50:31 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux

---Steps to Reproduce---
 Send lots of traffic on a busy workload.

Fix for reported issue upstream commit 9aaae044abe95de182d09004cc3fa181bf22e6e0
Fix for EEH related issue upstream commit 0c0e63410a393aae4b615849625f539db775d586

We would like to get those applied to both Ubuntu 14.04 updates and Ubuntu 14.10, please.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!
