New regression in v5.19-rc1. ----- Forwarded message from bugzilla-daemon@xxxxxxxxxx ----- Subject: [Bug 216109] New: Steam Deck fails to boot when E820 entries clipped out of _CRS https://bugzilla.kernel.org/show_bug.cgi?id=216109 Summary: Steam Deck fails to boot when E820 entries clipped out of _CRS Kernel Version: v5.19 Guilherme G. Piccoli reported that v5.18 boots fine on Steam Deck, but v5.19-rc1 does not. He bisected it to 4c5e242d3e93 ("x86/PCI: Clip only host bridge windows for E820 regions") [1]. A quirk similar to [2] that disables E820 clipping makes v5.19-rc1 work again. The reason why v5.18 (which always does E820 clipping by default) works, while v5.19-rc1 (which also does E820 clipping on this platform) does not has not been explained yet.
