--- Comment #18 from Guillaume Pothier <[email protected]> 2010-12-02 20:32:10 --- pci_nocrs seems to mitigate the problem. Actually, I was going to say it makes the problem disappear because I was able to perform 15 suspend/resume cycles, but when attempting the 16th to get the contents of /proc/iomem, it powered off... Anyway, here are the contents of /proc/iomem before and after a suspend/resume cycle, on 2.6.37-rc without pci=nocrs (or do you need it with pci=nocrs?): gpoth...@tadzim:~$ cat /proc/iomem
