** Description changed: + [SRU Justification] + + [Impact] + The memory card can be detected and mount correctly when the system starts with the card inserted. But it will fail to be detected at the subsequent re-plug. It only happens on particular Realtek older PCI interfaced card readers. The RTL8411B (10ec:5287) is reported problematic for this issue. + + [Fix] + Found the commit 121e9c6b5c4c ("misc: rtsx: modify and fix init_hw function") in 5.11.0-rc1 introduces this regression. The fix from upstream use the old ASPM control for particular realtek card reader models: 8411 5209 5227 5229 5249 5250. + + [Test] + Verified on the Realtek PCI interfaced card reader RTL8411B and verify whether the memory card can be detected for each re-plug. + + + [Where problem could occur] + The regression can be considered as low since the fix has specified separate ASPM control for particular Realtek Card Readers. + + + ========== Original Bug Description ========== + If I boot my laptop with an SD card (actually SDXC) in the MMC slot the system sees it and I can mount and use it. If I then unmount it, remove it then re-insert it I get this in the system ,og: [ 194.673108] mmc0: card e624 removed [ 205.462065] mmc0: cannot verify signal voltage switch [ 205.567479] mmc0: error -84 whilst initialising SD card and the card cannot then be used. It was OK in groovy. It's failing in hirsute.
