VT82C586B PIPC Bus Master IDE (rev 06) 00: 06 11 71 05 07 00 90 02 06 8a 01 01 00 20 00 00 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 01 e4 00 00 00 00 00 00 00 00 00 00 06 11 71 05 30: 00 00 00 00 c0 00 00 00 00 00 00 00 ff 01 00 00 <---!!! If I get this correctly it wants to have 0xff interrupt line. If this is correct how can this be possible and can I do anything about it. [And could this be the reason for my bad transmissions times.] I have: -QDI Kudoz 7x board with VIA KT400 chipset (vt8235) -2.4.18 kernel (stock RedHat 8) also tried 2.4.21pre3 and 2.4.21pre3-ac4 And I also tried upgrading the BIOS and the problem didn't go away. At boot time I get: ------------------- Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller on PCI bus 00 dev 89 PCI: No IRQ known for interrupt pin A of device 00:11.1.
