Ok, looks like the -t parameter did not work out...

As I am looking thru the kernel config, found this:

[ ] Message Signaled Interrupts (MSI and MSI-X) 

Its not enabled.
So, can one of you with this problem enable MSI (CONFIG_PCI_MSI) in the kernel 
and test if that will work?

Browsing thru the kernel doc:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/MSI-HOWTO.txt;hb=HEAD

Im not sure if there are downsides if we enable this as default..
"Use of PCI MSI interrupts can be disabled at kernel boot time                  
                                                                    
by using the 'pci=nomsi' option.  This disables MSI for the                     
                                                                   
entire system."

Soh, we have alternative options to use...


Im compiling this into my kernel here now to give it som testing, 
but I do not have the MSI problem and I do not have a Dell Opti 755 :-)
