** 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.
