Hi,
I bisected a sata regression to commit a57c1bade5a0ee5cd8b74502db9cbebb7f5780b2
The details are as follows:
System is a powerpc (g5)
CONFIG_ATA=y
# CONFIG_ATA_NONSTANDARD is not set
# CONFIG_SATA_PMP is not set
# CONFIG_SATA_AHCI is not set
# CONFIG_SATA_SIL24 is not set
CONFIG_ATA_SFF=y
CONFIG_SATA_SVW=y

And when booting with the commit applied, I instead get a whole lot of
messages like this (this is the first one, copied by hand):
