The first System, where harddisc don't work at all with the new stack: Nvidia NForce2 Ultra Chipset; 1GB RAM; XP-M 2600; FW-Controller is PCI addon card; lspci says Via Vanilla Kernel 2.6.22, apic, Preempt, Dynamic Tics. hmm something else interesting? > > On another PC same problem, but replugging one or two times get the thing > > working. > > Which controller does this other PC have?
