https://bugzilla.kernel.org/show_bug.cgi?id=215993 --- Comment #7 from Andy Shevchenko (andy.shevchenko@xxxxxxxxx) --- So, this line fails: https://elixir.bootlin.com/linux/v5.19-rc4/source/drivers/spi/spi.c#L2399 Can you double check that is true in your case? If so, it mean that by some reason we can't find registered SPI controller. You may add a debug print before this https://elixir.bootlin.com/linux/v5.19-rc4/source/drivers/spi/spi.c#L4224 dev_info(dev, "%s <--> %s\n", acpi_dev_name(ACPI_COMPANION(dev->parent)), acpi_dev_name(data)); Meanwhile can you attach file from `acpidump -o ux3402za.dat` or if there is known publicly available dump (GitHub?) share that link? P.S. Regarding booting v5.19-rc5, possible this thread will shed a light https://lore.kernel.org/all/272584304.305738.1657029005216@xxxxxxxxxxxxxxxxxx/ -- You may reply to this email to add a comment.
