Ah, yes. I changed addkcmdline but checked kcmdline for value. But that does not help, I still see kernel panic. On the other hand, if I take existing initrd, unpack it, remove driver, pack it back, node boots properly. But this is obviously not a good way to rebuild initrd.

Cheers,

Thank you, but that attribute gets overwritten when I do nodeset install.

No need for custom initrd, that will suppress the driver.

    Hi,

    We have some nodes with Tesla GPU devices that do not boot with
    RH 6.1
    (kernel panic on loading nouveau drivers). What is the best way
    to set
    kernel command line and custom initrd? I used boottarget table,
    but that
    requires me to hardcode ks attribute like:
    ks=http://10.0.101.206/install/autoinst/compute-gpu-a1-004-p
    Is it possible to set it for the group of nodes?

    Second question is how do I build working  initrd with redhat 6. Even
    with dracut-network package, it complains about empty or not present
    root. I tried setting root=dhcp (does not work) or
    root=anaconda-kickstart (not even understood).

    Cheers,
    Yuriy
