Does this still show with the latest kernel available by up2date / rawhide ?
Several aic7xxx performance bugs are fixed since the original wolverine-kernel.

Comment 2 Eugene Kanter 2001-03-12 20:46:20 UTC
tested with 2.4.2-0.1.25. got speed over 8 meg/sec which is normal.

Comment 3 Arjan van de Ven 2001-03-12 20:58:55 UTC
sounds fixed to me, closing
