Issue #297 has been updated by Martin Kepplinger.
just for the record, `watch -n 1 "cat /proc/interrupts | grep -i pci"` shows that rtsx_pci interrupts are being generated on card insert and removal. And this is them (debug output enabled using `echo -n 'file drivers/mmc/* +p' > /sys/kernel/debug/dynamic_debug/control` )

---------------------------------------- Bug #297: T440P card reader is broken. https://ticket.coreboot.org/issues/297#change-1332
* Author: Jamal Wright * Status: New * Priority: Normal * Start date: 2021-03-03 ---------------------------------------- I've been trying to figure out the reason why the card reader detects but doesn't work and crashes windows. Wanted to track this bug outside of the mailing list since that will probably get lost. I've even cross compared to the X250 and everything looks normal. Am I missing a GPIO? Is there something wrong with the PCIE detection? Perhaps a conflict with the wifi which is on the same PCIE root? Building off master as of 3/3/21
I get this in kernel:

I've attached CBMEM logs as well. A bit out of ideas, just sitting with fingers crossed hoping a haswell or lynxpoint commit fixes it :)
