That kernel consistently _died_ when trying to start xdm. Xorg logs for both cards ended like this: (II) LoadModule: "pcidata" (II) Loading /usr/X11R6/lib/modules/libpcidata.a Of course the last block of the log may be lost, as this crash blocked even sysrq so it is reasonable to assume that the disk drivers and filesystems froze up too. I can retry this with a syncronously mounted /var, if the last lines of the Xorg logs might be interesting. Helge Hafting
