It would be extremely helpful to get the output from the work MPC8540 for lspci and cat /proc/pci.
Also, I forget if 2.6.11 has CDS VIA support, but if it does you can try disabling it by commenting out the calls to: mpc85xx_cds_enable_via() & mpc85xx_cds_fixup_via() in arch/ppc/syslib/ ppc85xx_setup.c and see what happens. - k On Aug 10, 2005, at 10:58 AM, Bizhan Gholikhamseh \\((bgholikh\\)) wrote: > <<pci_boot.pdf>> Kumar, > We do not support or care about VIA IDE controller.
