| |
Dell Latitude D610, Pentium M @ 1.86Ghz, 2GB RAM running uptodate FC4. 100% reproducable since 2.6.15-git6, no problem up to -git5. 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.
Card is, according to lspci -v,
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) (prog-if 00 [VGA]) Subsystem: Dell: Unknown device 0182 Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at dff00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ec38 [size=8] Memory at c0000000 (32-bit, prefetchable) [size=256M] Memory at dfec0000 (32-bit, non-prefetchable) [size=256K] Capabilities: [d0] Power Management version 2
Doesn't happen on -git6 on my older laptop (Latitude C640, Pentium IV @ 1.8Ghz, 1GB RAM, Radeon Mobility 7500), so it definitely is hardware-related.
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:

Something to do with the PCI Express stuff ?
Available for more detailed info and/or testing to interested parties :)
Thanks in advance, ciao,
