Bug Description

== Comment: #0 - Vaibhav Jain <email address hidden> - 2018-04-09 04:58:46 ==
---Problem Description---
CXL driver reports a warning message when performing cache flush. This is due to data-cache not present on some of the CAPI adapters hence the data-cache operation fails and results in this error.

"WARNING: cache flush timed out"

Contact Information = Vaibha Jain <email address hidden>

---uname output---
4.15.0-12-generic

---Additional Hardware Info---
Nallatech Flash GT+ adapter

Machine Type = Boston-LC

---Debugger---
A debugger is not configured

---Steps to Reproduce---
* Make sure that cxl module is loaded
* Issue command 'rmmod cxl'
Error seen in the kernel logs:
dmesg
[ 1203.791963] pci_bus 0006:00: busn_res: [bus 00] is released
[ 1203.792096] cxl afu0.0: Deactivating AFU directed mode
[ 1208.792711] cxl card0: WARNING: cache flush timed out!

The fix for this issue was merged to the mainline kernel via commit:

94322ed8e857 cxl: Check if PSL data-cache is available before issue flush request

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-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

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.
