Comment 74 for bug 355155

I have recently switched over from Gutsy to Jaunty (fresh install), and
the system started to freeze randomly, although the REISUB combination
usually worked.

After downgrading to 2.4.27, the system ran stable again for several
days, but eventually locked up too. Then I tried the standard Jaunty
kernel (2.6.28-11-generic) once more, and the system was mostly stable
again (froze "only" twice in the past week). However, after the last
freeze yesterday, it has become unusable again; starting Gimp and
Firefox froze the system every time (with and without plugged network
cable, with and without acpi option, with and without activated
swap), although I had used these programs a lot over the last week without
problems.

These freezes were also hard freezes, ie. the REISUB combination did
not work, Caps Lock did not blink, and even the mouse cursor was frozen.

I am now using the PPA mainline kernel 2.6.27-02062710-generic again,
and this seems to work; for now. As far as I remember, I have not
installed anything in the past few days, so it has been essentially the
same system all the time, and the computer has been running flawlessly with
Gutsy for over a year now.

The computer is a Dell Optiplex 745 (Intel Core Duo, ATI Radeon X1300/X1500),
and I am not using any proprietary drivers.
