Hi,
I have been talking on this subject privatly with Joe too, but
now in public again.
> 1) it is SMP specific and seems to be 2.2 specific (there are
> other problems in 2.0 that can cause X to crash this is not the
> same crash is not = freeze/mouse wacko..different bug)
Seems correct.
> 2) it is happening with version of X 3.3.2.3 or later
Don't know yet
> 3) it is not serial or PS/2 specific
Correct.
> 4) it is not hardware or software cursor specific
Correct.
> 5) it may have have something to do with shared interupts
Could truely be.
> 6) it seems like X is loosing its mouse thou..
Correct.

I'm not going to dig into this theory, yet. First of all I wrote
a patch to be able to switch a Edge interrupt to Level or to
switch of the use of IO-APIC for a certain interrupt number using
kernel parameters.
Joe and I are already using this patch.
It will help narrowing the problem (... so I hope)
Now what I ask people:
I want to see /proc/interrupts of people with problems. And I
want to know whether the use NFS and have problems with NFS too.
Further I like to know if someone is using a seperate IO card, or
the (nowadays) commonly used onboard chips.
I ask too the type of nw adapter, and the bus on which it is
(ISA/PCI/PCMCIA (Cardbus)) Lastly if possible:
the /proc/interrups closely before and closely after the crash.
(And of course: kernel version, type of hw used)
But PLEASE don't send this to the list. Instead send it to
[EMAIL PROTECTED] or [EMAIL PROTECTED]
Short explanation on what MAY be happening:
if a interrupt is not handled in the correct way (see edge/level/xtpic
differences), this may cause nasty races and a rather large flow
of interrupts, that are not caused by the mouse.
The network (NFS) may be affected by this problem too.
What I will do:
If the switching of the interrupt handling does help, there may
be a bug in the io-apic code, or another common encountered BIOS
bug (not unlikely). In that case I'll take up with mingo.
If people do want to have that patch, I can send them. But I would
prefer not to spread it in public, as it's just a quick hack and
a temporarily solution, not THE sollution.
Greetings,
Jos van de Ven
