FYI:
5.12 Merge window delayed

[Posted February 16, 2021 by corbet]
Those of us who are watching the mainline kernel repository may have been wondering why it appears that no pull requests for the 5.12 merge window have yet been acted upon. The problem, it seems, is power outages caused by the severe winter weather in the US Pacific northwest. Until that gets resolved, which could take a few days, the 5.12 merge window is likely to remain on hold.

Hi Musa,

Many many thanks for testing. I reverted the pas_pci_init patch because this function has been moved to the device tree adoption but unfortunately the X1000 doesn't have it in its device tree.

Download: linux-image-5.12-alpha3-2-X1000.tar.gz

Please test it.

Thanks,
Christian

Hi Musa,

Thanks a lot for testing! I appreciate it very much. I have reported this issue to the kernel developers.
