as my machine is now up for nearly 14 days, I'll venture another
explanation that at least for my setup looks like it's causing (helping
to cause?) the lockups.
Scenario:
As said before, there were 3 isdn cards in it. These cards had the habit
to generate lots of interrupts. Lots. More than the timer on board
(every 8ms, if I'm not mistaken). Well, I exchanged everything. I even
exchanged the isdn cards (now there are only two, as I didn't have
enough handy then). With the first try, one of the new cards did this
interrupt-fire also. You guess, a lock after 7 days. I installed a new
HiSax driver that knew how to switch of those irq in these cards. Well,
I'm now at nearly 14 days uptime.
So, under a machine with moderate load, this irq fire seems to upset the
kernel so much that it does something to get some free time?
Anybody wants to comment?
