U160 on Adaptec 39160

[Margit Schubert-While <margit@margit.com>]

Hi,
	Anybody know why I'm not getting 160MB transfers ?
	Kernel is Suse 2.4.19
	MB is Intel D845PESVL + 2.4 P4 + 512MB DDR333 ram.
	Adaptec card is in 3rd PCI slot.
	AGP ATI 7500 vga
	2 x U160 disks on channel B with special U160 cable and actively
	terminated.
	DVD + DAT on SE channel A. Nothing on U160 channel A.
	Snips under from log and /proc
	Thanks
	Margit Schubert-While
