Subject: 2.6.22.5 SATA Failure
Date: Sun, 26 Aug 2007 09:55:22 +0800 [thread overview]
Message-ID: <a2ebde260708251855j708d2b33hfce905f623597325@mail.gmail.com> (raw)
I have been using 2.6.21.1. It seems working well, that is, all my
disk partitions are mapped as "/dev/sda*" and the performance looks
good. After I upgrade to 2.6.22.5 with the exact same configuration,
all the disk device turn to "/dev/hda*" and the performance degrade
obviously.
While I boot with 2.6.21.1, the logs regarding disk are:

While booting with 2.6.22.5, the logs are:
Aug 26 09:30:04 localhost kernel: ACPI: PCI Interrupt 0000:00:1f.2[B]

It seems the dramatic change in libata.c incurs this failure.
