[Bug 1571798] [NEW] Broadwell ECRC Support missing in Ubuntu
Public bug reported:
Here is the problem statement from the Dell team:
When booting into Ubuntu 14.04.4 with a Broadwell CPU and an Intel Quick
Assist Card, the memory location that corresponds to ECRC is set to
0x01e0, when the BIOS is setting this location 0x00a0 pre-OS boot. This
causes the card to not function unless we implement the following
workaround using setpci.
“setpci –s AA:BB.C 160.w=0”, where AA:BB.C is the PCI Root Path for the
Intel Quick Assit Card.
We’ve verified the memory location is correct when booting to other
OSes, such as RHEL 7.2 and Windows Server 2012 R2.
If there is any information you can give as to why this may be occurring
in Ubuntu or where we may start to debug when the memory is changed, we
would appreciate it.
** Affects: linux (Ubuntu)
