Summary: i810 Driver and/or DRI cause hang on suspend under
2.6.12, xorg 6.8.2
Product: DRI
Version: DRI CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Kernel: 2.6.12
Platform: x86 Intel Centrino
Model: IBM Thinkpad X40
Xorg: 6.8.2 [FC4 RPM]
DRI-Common: 20050621 Snapshot
DRI-i915: 20050621 Snapshot
i810 Xorg Driver: included with DRI-i915 snapthot
Upon suspend (ACPI suspend to RAM), system hangs. If I revert to the i810 driver
included in the xorg 6.8.2 RPM, which deactivates DRI due to libdri version
mismatch (4.3.0 needed, 5.0.0 found) the system suspends cleanly. Various other
snapshots from the last 3 months of the i810 xorg driver show the same problem.
I will cross-post this bug under DRI as well.
For some reason, /var/log/messages isn't logging the oops (it logs some other
call trace from a warning) so I'll have to type this manually from the artifact
left on the screen on hang:
