--SLDf9lqlvOQaIe6s Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Still has the problem, on more hardware. Some more information: - One of these disk arries works well under 160M/s mode and RELENG_4 - One of these disk arries does not work at all under FreeBSD - Both of them works well under Linux and OpenBSD 3.6 (snapshot, i386) I'm trying to figure out why. It seems that OpenBSD's mpt(4) did something different from ours, however, I have hit some trouble porting their code due to busdma interface difference. I have a preliminary hacked port of OpenBSD's ``new'' features (without the firmware feature) but the result is not quite hearten. I try to do a more in-depth attempt on this.
