I reproduced this with vanilla 126.96.36.199 now, and I'm quoting
the entire message for the benefit of the guys over at
linux-poweredge at dell.com
To make it short, the suspend/wakeup loop didn't occur with 188.8.131.52
Still the bug happens, the box is apparently usable, but not
for the remote administration, so usability is quite shaky
a definition ;)
The relevant stuff is still at the url below, the two new interesting
(The netconsole issue is probably not related and I'll look into it
later, if ever, as we're not really using it...)
I also got a hint that disabling power management might help,
but that has to wait until tomorrow.. Anyone want to back
this theory? :)
