Hi again, * Andrew Vasquez > Hmm, MSI is enabled: Indeed - seems to be the default behaviour. > could you try disabling MSI via 'pci=nomsi' (I believe), we've dealt > with a large number of problem reports where customers reported 'odd' > behaviours (no interrupt routining) with several motherboard > chipsets. At least it could be another useful datapoint... The system has now been up for 58 hours straight with MSI disabled per your suggestion. This is almost a new record, usually it has crashed once per day or more. I won't open the champagne before a week more has passed, but this looks _very_ promising! Thank you very much for your help in tracking this down! Be sure to let me know if you want any more information and I'll see what I can do. The system isn't yet back in full production, so I have a small window of opportunity to reproduce the problem, test patches, and so on.
