Title:
efifb broken on ThunderX-based Gigabyte nodes
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Artful:
Fix Released
Bug description:
[Impact]
The following error is reported on boot:
[ 6.290553] pci 0004:21:00.0: BAR 0: failed to claim resource for
efifb!
This results in the efifb not being activated at boot. On this
platform, the same device will be initialized by the astdrmfb driver
later in boot, so this isn't fatal, so the real SRU justification here
is getting rid of the error message. It is possible that there are
platforms where the efifb is behind a PCI bridge, and there is no
accelerated alternative that will load later. This (theoretical) issue
is most likely to impact d-i installs, where only a subset of fb
drivers are included.
[Test Case]
dmesg | grep "failed to claim resource for efifb"
[Regression Risk]
The fix for this has been upstream since v4.14 with no known regressions. The
driver is only used on EFI systems, which limits the risk to a subset of
x86/ARM platforms. Regression tested on a Dell PowerEdge T610 (x86/UEFI).
I have a test fix in ppa:dannf/efifb for regression testing.
