Public bug reported:
[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. I have a test fix in
ppa:dannf/efifb for regression testing.
