RTS5227

[Sniki]

Hi @0xFireWolf.

I just checked the readme and i do have a RTS5227 card reader on my T440/T440S/X240/T440P laptops that i have.

Right now i am running latest release of Big Sur on my T440P;
The system would randomly kernel panic/instant reboot and i noticed once it boots up again, it shows on the apple problem report that it’s this kext, i noticed that logs are incomplete on the known issues section.

If you don’t mind just giving me quick steps on how i would normally collect the logs for your case, i would be able to test and provide logs to fix the issues.

Thanks in advance.

@Sniki I'm running Mojave with my T440s (which uses the same RTS5227 card) alongside the latest release of this kext (0.9.7). I have not had any KPs with this kext installed. See issue #18 where @0xFireWolf helped me debug and add better support for this card, which might also help you generate logs for him to further investigate.

I have my kext installed via injection using Clover bootloader, and I also have RealtekCardReaderFriend installed although I do not think it's necessary.

@joshuaseltzer then it seems that the issue is specific to newer macOS versions, it happens to me on Big Sur and Monterey.
Same scenario happened on my X240/T440P/T440S from what I've tested so far, i also add RealtekCardReaderFriend.kext as it makes your card reader show on System Report > Card Reader.
Apart from this random intermitent Kernel Panic into an instant reboot, the kext seems to be working perfectly fine.

Thanks for the support.

Then maybe it is related to the specific macOS version, or maybe the bootloader (yes, I'm still on Clover).

Also, I should mention, I rarely use the SD Card reader on my T440s. I've probably only used it 2 or 3 times since the kext was released. So if your issue is only when a card is inserted, maybe mine would have the same issue. My system has had almost 8 months of uptime at this point though, so it's pretty rock solid stable.
