Description of problem: This bug is opened at the request of CentOS developers. Closing the lid and then reopening on Dell Latitude D820 gives X backtrace. This was working with CentOS 5.1, so it appears to be a regression. It happens with both the "i810" and the new, experimental "intel" driver. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.1.1-48.41.el5_2.1 How reproducible: Always Steps to Reproduce: 1. Start X session (startx) 2. Close lid of notebook 3. Open lid and observe backtrace Actual results: The following was observed on the screen: SetGrabKeysState - disabled SetGrabKeysState - enabled I830PMEvent: Capability change Backtrace: 0: /usr/bin/X(xf86SigHandler+0x81) [0x80c3701] 1: [0xe29420] 2: /usr/lib/xorg/modules/drivers/intel_drv.so [0x5cc06b] 3: /usr/lib/xorg/modules/drivers/intel_drv.so(intel_xf86InitialConfiguration+0xf2a) [0x5cf3da] 4: /usr/lib/xorg/modules/drivers/intel_drv.so [0x5ad0a0] 5: /usr/bin/X [0x80e2b13] 6: /usr/bin/X(xf86HandlePMEvents+0xb5) [0x80e2c75] 7: /usr/bin/X(xf86Wakeup+0x153) [0x80c4bc3] 8: /usr/bin/X(WakeupHandler+0x59) [0x808c229] 9: /usr/bin/X(WaitForSomething+0x1b9) [0x81a0d79] 10: /usr/bin/X(Dispatch+0x8d) [0x808804d] 11: /usr/bin/X(main+0x485) [0x806fab5] 12: /lib/libc.so.6(__libc_start_main+0xdc) [0x140dec] 13: /usr/bin/X(FontFileCompleteXLFD+0x1ed) [0x806edb1] Fatal server error: Caught signal 11.

This is almost certainly fixed in 5.2 or later, significant updates to the i810 driver happened since 5.1. However, no further hardware enablement updates are planned for RHEL5's X stack. If this issue is still present in RHEL6, please update the affected product version and reopen this bug.
Correct; the Dell Latitude D820 has since been reloaded with RHEL 6, and the OS suspends correctly when the lid is closed; the kernel panic no longer occurs.
