Hello all! After using my laptop reaches more than about 20 hours of uptime (and I have a couple of suspend/resume cycles in between by closing the lid) the next suspend fails like this:
The system never sleeps, instead the kernel dmesg stops at: > PM: Syncing filesystems ... done. > PM: Preparing system for mem sleep and never makes it to > Freezing user space processes ... (elapsed 0.01 seconds) done. > Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. > PM: Entering mem sleep > ... Furthermore, if I open the lid I find that X has crashed, my whole session is lost and I am back at the display manager to login. The only fix I have found to this problem is either -> Never suspend by closing the lid, or -> Always kill the X server every about 10-12 hours I am using a Lenovo T420 with HD3000 onboard and no nvidia present. There is an active thread here https://bbs.archlinux.org/viewtopic.php?id=144381, ignore the title saying about linux 3.4, it happens with kernels back to 3.0 (and probably older) It happens with -> xorg-server-1.12.3 -> xorg-server-1.12.3.901 -> xorg-server-1.12.4 after the failed suspend, the end of /var/log/Xorg.0.log is this [ 7078.130] (II) AIGLX: Suspending AIGLX clients for VT switch [ 7081.997] (II) AIGLX: Resuming AIGLX clients after VT switch [ 7082.050] (II) intel(0): EDID vendor "LGD", prod id 738 [ 7082.050] (II) intel(0): Printing DDC gathered Modelines: [ 7082.050] (II) intel(0): Modeline "1600x900"x0.0 96.00 1600 1648 1680 1728 900 903 908 926 -hsync -vsync (55.6 kHz eP) [ 7085.063] (--) synaptics: SynPS/2 Synaptics TouchPad: touchpad found [ 8611.400] [ 8611.400] Backtrace: [ 8611.404] 0: /usr/bin/X (xorg_backtrace+0x36) [0x560306] [ 8611.404] 1: /usr/bin/X (0x400000+0x164039) [0x564039] [ 8611.404] 2: /usr/lib/libpthread.so.0 (0x7fe2ecf1c000+0xf170) [0x7fe2ecf2b170] [ 8611.404] 3: /usr/bin/X (XIChangeDeviceProperty+0x1b8) [0x502d58] [ 8611.404] 4: /usr/bin/X (DisableDevice+0x20f) [0x42d8ff] [ 8611.404] 5: /usr/bin/X (xf86Wakeup+0x494) [0x46fa44] [ 8611.404] 6: /usr/bin/X (WakeupHandler+0x6b) [0x43848b] [ 8611.404] 7: /usr/bin/X (WaitForSomething+0x1a4) [0x55d744] [ 8611.404] 8: /usr/bin/X (0x400000+0x34281) [0x434281] [ 8611.404] 9: /usr/bin/X (0x400000+0x23615) [0x423615] [ 8611.404] 10: /usr/lib/libc.so.6 (__libc_start_main+0xf5) [0x7fe2ebdcb725] [ 8611.404] 11: /usr/bin/X (0x400000+0x238ed) [0x4238ed] [ 8611.404] [ 8611.405] Segmentation fault at address 0x11 [ 8611.405] Fatal server error: [ 8611.405] Caught signal 11 (Segmentation fault).

On resume, the reboot/shutdown continues. If you need more info, please request it, I will make it available. Thanks and sorry for the long post. _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: [email protected]
