Summary: [GEM 2.6.28-rc7] X freezes, warning/oops in i915 driver
after resuming from suspend
Product: DRI
Version: XOrg CVS
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: critical
Priority: medium
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
On my Lenovo Thinkpad SL300, after resuming from suspend-to-ram, X freezes
hard, making the keyboard unusable, and forcing me to hard-reboot unless I am
near another machine that I could ssh from. Looking at dmesg, it looks like the
error is in the new GEM memory manager in the i915 driver.
Hardware:
Lenovo Thinkpad SL300
Intel GM45 Express Chipset
Software:
2.6.28-rc7-git1 kernel (64-bit)
libdrm-2.4.2 pre from Git master on 2008-12-03
xf86-video-intel-2.6 pre from Git master on 2008-12-03
mesa-7.3 pre from Git master on 2008-12-03
xorg-server-1.5.2
dmesg log #1 (after resuming during a Gnome session)
