As mentioned in my previous reply to Naresh, this is a new driver added in 6.1. Your board was working before so this should not be the driver needed for it. > However, reverting patch 33629d35090f ("ata: ahci: Add DWC AHCI SATA > controller support") > from next-20221013 was a success, kernel booted and the 'mkfs.ext4' cmd was > successful. Which is very strange... There is only one hunk in that commit that could be considered suspicious: diff --git a/drivers/ata/ahci_platform.c b/drivers/ata/ahci_platform.c index 9b56490ecbc3..8f5572a9f8f1 100644 --- a/drivers/ata/ahci_platform.c +++ b/drivers/ata/ahci_platform.c @@ -80,9 +80,7 @@ static SIMPLE_DEV_PM_OPS(ahci_pm_ops, ahci_platform_suspend, static const struct of_device_id ahci_of_match[] = { { .compatible = "generic-ahci", }, /* Keep the following compatibles for device tree compatibility */ - { .compatible = "snps,spear-ahci", }, { .compatible = "ibm,476gtr-ahci", }, - { .compatible = "snps,dwc-ahci", }, { .compatible = "hisilicon,hisi-ahci", }, { .compatible = "cavium,octeon-7130-ahci", }, { /* sentinel */ } Is your board using one of these compatible string ?
