Public bug reported:
Binary package hint: linux-image-2.6.35-27-generic
Normally, I can suspend/resume with no problems (other than known issues with
kontact / kio_imap4) no matter which kernel I am using. However, recently I
have noticed that whenever I have kate (kde advanced text editor) open, my
computer hangs (black screen, completely unresponsive) just before I would
expect it to go fully into sleep mode. After a while the fan starts blowing hot
air at maximum speed so I assume the processor has gone into an infinite loop.
I tested some of the past kernel versions I have in my /boot partition and
found that it works for versions before 2.6.35-24
In summary:
2.6.35-22-generic : suspend always OK
2.6.35-24-generic : suspend always OK
2.6.35-27-generic : Hangs when running kate, otherwise OK
2.6.35-28-generic : Hangs when running kate, otherwise OK
Steps to reproduce:
Reboot into kernel version 2.6.35-2[78]-generic
run kate (N.B. the hang still happens even if there are no files open in kate)
close laptop lid or select 'sleep' from K menu
