Description bitshifter 2008-09-24 07:48:54 UTC
Latest working kernel version: Unknown
Earliest failing kernel version: Unknown
Distribution: Slackware (current)
Hardware Environment: Lenovo Thinkpad T61
Software Environment:
Problem Description:
As a base kernel config I am using http://dotimes.com/download/config-t61

With that configuration, if I turn CONFIG_NO_HZ on resume fails leaving me with a blinking half moon and a flashing text mode cursor in the upper left hand part of the screen.

Steps to reproduce:
make oldconfig with the mentioned kernel configuration saying yes to all 1 question.

make menuconfig - turn on the tickless kernel feature

make and install

s2ram -f -a3

perform some interrupt to wake the computer (eg press Fn key)

What other information is needed/desired for this bug?  What steps can I do to help debug this?

First, can you check the latest -git kernel please?
Comment 2 Thomas Gleixner 2008-09-24 12:16:26 UTC
Can you please please try 2.6.27-rc7 ?


Comment 3 bitshifter 2008-09-24 13:59:00 UTC
2.6.27-rc7-git2 seems to have this problem fixed.  I used the config file from above and made reasonable answers to the new functionality and turned on CONFIG_NO_HZ
