sdhci_pci fails to probe in domU that has the device passed to it with:
sdhci-pci 0000:00:06.0: probe with driver sdhci-pci failed with error -22
The reader works fine in dom0.
I’ve disabled memory ballooning for this domU.
I’ve tried to enable permissive mode and no strict reset for the device.
HW: Novacustom NV41
DomU runs on Debian 12 template.
The same happens when using different kernels:
- dom0 supplied (6.10.10-1-fc37)
- domU supplied (linux-image-6.1.0-25-amd64 6.1.106-3)
- custom build vanilla Linux from recent master (ad46e8f95e93) with config mostly copied from Debian kernel (+dbg options enabled)

Seems that somebody had the same issue but didn’t pursue it: HCL - Tuxedo InfinityBook S 15 - Gen8 (NS50AU) Unfortunately in my case USB card reader is useless.
Anybody got idea how to fix/debug this?
