So it might be from the PCI subsystem :-( [ 6.167106] sdhci: Secure Digital Host Controller Interface driver [ 6.167108] sdhci: Copyright(c) Pierre Ossman [ 6.194731] ehci_hcd 0000:00:1a.0: cache line size of 64 is not supported [ 6.195140] ehci_hcd 0000:00:1a.0: irq 16, io mem 0xf6970000 [ 6.196423] sdhci-pci 0000:03:00.1: SDHCI controller found [1180:e822] (rev 3) [ 6.196429] sdhci-pci 0000:03:00.1: found 1 slot(s) [ 6.196447] sdhci-pci 0000:03:00.1: PCI INT B -> GSI 19 (level, low) -> IRQ 19 [ 6.196451] sdhci-pci 0000:03:00.1: BAR 0 is not iomem.
