Bug 12587

Summary: using >= linux-2.6.26-gentoo-r4 machine hangs when start hibernating
Product: Power Management Reporter: Karlis.Repsons
Component: Hibernation/SuspendAssignee: power-management_other
Status: CLOSED DUPLICATE    
Severity: normal CC: lenb, rjw
Priority: P1    
Hardware: All   
OS: Linux   
Kernel Version: 2.6.26 Tree: Mainline
Regression: Yes
Bug Depends on:    
Bug Blocks: 7216    

Description Karlis.Repsons 2009-01-31 09:13:59 UTC
Latest working kernel version:2.6.25-gentoo-r7
Earliest failing kernel version:linux-2.6.26-gentoo-r4
Distribution:gentoo
Hardware Environment:x86-64
Software Environment:running gentoo, no Xorg in test
Problem Description: 

so I try doing this:
echo 17179869184 > /sys/power/image_size
echo disk > /sys/power/state

and it results in hang with 2.6.26. Console gets completely blank, no disk access and for more than minute like that, so I have to hard-reset the system. Also can't access with ssh during that hang.

Steps to reproduce:
get Asus P5Q-E with core2 duo, install gentoo, compile kernels mentioned above and for newer one take config of .25, make mrproper && cp /path/to/config.25 .config && make menuconfig && make -j3 && make modules_install 
I changed nothing in menuconfig. and do echo ...

Comments:
Can attach .config or send by mail, but there is little of helpful in it, I think. No nvidia was compiled for testing kernels, so no binary drivers were loaded.

Please try 2.6.29-rc4 when it's out and let me know whether it works.  If possible, please test kernels from kernel.org rather than distro kernels.
