Hello,
After updating to the 5.10 kernel, my laptop will spontaneously poweroff
when idle after some time (between 30 minutes and three days).
I have bisected it down to a rtsx driver update in 7c33e3c4c79a:
commit 7c33e3c4c79ac5def79e7c773e38a7113eb14204

Add rts522a L1 sub-state support
Save more power on rts5227 rts5249 rts525a rts5260

I'm not sure whether this is a driver or hardware problem and am seeking
feedback on how to further debug the issue.
FWIW the problem does not seem to reproduce on an AMD ThinkPad T14 Gen 1
with the same RTS522A PCIe card reader (on stock Arch 5.10.16 kernel).
Thanks & happy hacking,
Marius
