Hello, Someone posted a bug report for UFS on an sdm850 tablet: https://bugzilla.kernel.org/show_bug.cgi?id=204685 If I'm reading the boot logs right, this board is EFI rather than DT. (Lee: EFI on qcom is one of your areas, right? The UFSHC driver is DT-aware, but is it EFI-aware?) [ 0.000000] efi: memattr: Unexpected EFI Memory Attributes table version -1347440721 I suppose this may be safely ignored? [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.2.0-99-generic root=UUID=66e85825-5c21-4120-b4ee-e17e4cdc1e58 ro efi=novamap ignore_loglevel clk_ignore_unused pd_ignore_unused console=tty0 IIUC, the kernel is supposed to boot successfully even without "clk_ignore_unused pd_ignore_unused" (tangential, unrelated) Bjorn, any ideas? Ever see this issue? Regards.
