Subject: 2.6.23-rc2-mm2: sata disk going slow
From: Hugh Dickins <hugh@xxxxxxxxxxx>
Why is the G5 so slow with 2.6.23-rc2-mm2? hdparm -t shows 1.8MB/sec
instead of 58MB/sec. alpm-increase-number-of-allowable-device-flags.patch
(raising ATA_DFLAG_CFG_MASK) turns out to be the guilty party: though the
problem doesn't appear until the next patch, which adds ATA_DFLAG_IPM as
the same bit as ATA_DFLAG_PIO. Here's a hotfix against top of -rc2-mm2.
