Description Thomas Roessler 2005-10-01 18:38:11 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
2.6.13-1.1526 recognizes the hard drive in a Thinkpad T43 as an ATA drive (which, technically, it seems to be). Attempting to turn on the using_dma flag fails; the hard drive has a throughput of 3MB/s.

With prior Fedora Core kernels, the drive was recognized as an SATA drive, with about ten times the throughput.
