Has anyone run the promise TX4 on an SMP system? I get lost interrupts on the first two interfaces (e.g. below). Interestingly, /proc/interrupts shows 0 interrupts for the offending interfaces: 24: 0 0 IO-APIC-level ide2, ide3 25: 8128728 8128842 IO-APIC-level ide4, ide5 The box is a SuperMicro P3TDE6, a ServerWorks III HE SL-based board, with 2xPIII CPUs. Any ideas / experiences? Regards, Ben Uniform Multi-Platform E-IDE driver Revision: 6.31 ...
