The 2.4 driver was forcing the data rate to auto negotiate, while the 2.6 (or 8.x series) driver was honouring the NVRAM setting which was at the default 1 Gbps. Changing to auto negotiate in the qlogic BIOS fixed the problem. > > On a side note: Your driver reports 33 MHz PCI - if this is in a > 32-bit slot, isn't 2Gbps more than the bus can handle? It's a 64 bit slot.. -jf
