Bug#494036: linux-image-2.6.26-1-686: same erractic freeze on my thinkpad t60 with 2.6.25 and 2.6.26
 

Package: linux-image-2.6.26-1-686
Version: 2.6.26-4
Followup-For: Bug #494036


Just to add another report. I have the same erratic freezes on my Thinkpad T60
with 2.6.25 and 2.6.26. I hope this is the same problem as reported in this bug
report but I have nothing to confirm it.

At the moment, I cannot use a kernel > 2.6.24 because of those freeze.

Feel free to ask for more details or tests if needed.
