Subject: Stack dump from GIT HEAD if CONFIG_ATA_SFF is not set

I am using kernel 2.6.27-Linus-03151-g4480f15b-dirty. On booting a system built
with CONFIG_ATA_SFF not set, the following appears in my dmesg output. The
"dirtiness" of the kernel is due to some code included to trace down messages
coming from the usb system, and is not involved here. If CONFIG_ATA_SFF=y, the
message does not appear. From Google results, it seems that this parameter
should be set for most systems, but one should get clean runs without it.
