Hi,
I want to try and debug why the 2.6.17 kernels hang on on my system when
rebooting from a suspend-to-disk. 2.6.16 ones seems fine. Unfortunately the
hang happens early, just after the "resuming from /dev/hda9" message, so I
don't get much in the way of info. I have to hard reset.
Can anyone suggest anything I can do to help debug this.
Are there any kernel options I could use to get more information out the the
kernel as it loads ?
Would it help if I rebuilt the kernel myself, turning on or off any options ?
Are there anything I can do when the system is hung - I've tried all the
control sequences I know to get it to tell me something.
ANY suggestions gratefully received - I would really like to try and get to
the bottom of this.
cheers Chris
