Log in to VT1, run startx, fire up a gnome-terminal, exit it, Desktop->Logout... at this point the mouse arrow stills and the box locks up, keyboard dead, no response to pings.

Diff'ing the dmesg boot log and the Xorg log from the latest working version to the latest available version, the relevant lines would seem to be these: [root@sandman ~]# diff /tmp/dmesg-2615git* | grep -v audit 1c1 < Linux version 2.6.15-git5 (asuardi@sandman) (gcc version 4.0.2 20051125 (Red Hat 4.0.2-8)) #1 Thu Jan 12 01:01:05 CET 2006 --- > Linux version 2.6.15-git7 (asuardi@sandman) (gcc version 4.0.2 20051125 (Red Hat 4.0.2-8)) #1 Thu Jan 12 00:48:04 CET 2006 [...] 78a79 > PCI: Bus #04 (-#07) may be hidden behind transparent bridge #03 (-#04) (try 'pci=assign-busses') 145c146 --- 157,159c158,160 < Allocate Port Service[pcie00] < Allocate Port Service[pcie02] < Allocate Port Service[pcie03] --- > Allocate Port Service[0000:00:1c.0:pcie00] > Allocate Port Service[0000:00:1c.0:pcie02] > Allocate Port Service[0000:00:1c.0:pcie03] [...] [root@sandman ~]# diff /tmp/Xorg-2615git* 6c6 < Current Operating System: Linux sandman 2.6.15-git5 #1 Thu Jan 12 01:01:05 CET 2006 i686 --- > Current Operating System: Linux sandman 2.6.15-git7 #1 Thu Jan 12 00:48:04 CET 2006 i686 [...] 2101,2103c2101,2103 < (II) I810(0): Allocated 4 kB for HW cursor at 0xffff000 (0x37c27000) < (II) I810(0): Allocated 16 kB for HW (ARGB) cursor at 0xfffb000 (0x35b28000) < (II) I810(0): Allocated 4 kB for Overlay registers at 0xfffa000 (0x35ae5000). --- > (II) I810(0): Allocated 4 kB for HW cursor at 0xffff000 (0x36b84000) > (II) I810(0): Allocated 16 kB for HW (ARGB) cursor at 0xfffb000 (0x36bf0000) > (II) I810(0): Allocated 4 kB for Overlay registers at 0xfffa000 (0x36b87000). 2121,2122c2121,2122 < (II) I810(0): [drm] added 8192 byte SAREA at 0xf8a5a000 < (II) I810(0): [drm] mapped SAREA 0xf8a5a000 to 0xb7f55000 --- > (II) I810(0): [drm] added 8192 byte SAREA at 0xf8af0000 > (II) I810(0): [drm] mapped SAREA 0xf8af0000 to 0xb7f77000 Something to do with the PCI Express stuff ?
