on bug 106671
from Alan W. Irwin
I have discovered this box became significantly less stable when there were two users displaying X directly on it (one with startx , one with startx -- :1) and using ctrl-alt-F1 and ctrl-alt-F2 to switch between the two local X servers that were displaying two different XFCE desktops via the RX 550 graphics card. After moving to that mode of operation we got the following results for uptimes before lockups: 1 day, 2 times 2 days, 1 time 3 days, 1 time For each of these 4 lockups I could not spot any relevant messages in the log files. But the substantially shorter uptimes for this method of using this box does appear to confirm there are still issues with the graphics stack for the RX550. But the graphics content being displayed by the two users is roughly similar so I don't understand why this mode of operation is so much less stable then if just one user is using the RX 550 while the other is using an X-terminal. (None of these lockups occurred anywhere near the times we switched between the two local X servers, but I suppose it is possible that switching sets up a condition that results in a lockup much later.) Anyhow, because of the increased instability I gave up on the two local X servers approach and went back to the one local X server and one X-terminal approach, and with that approach we got an uptime of a week before the system locked up. That lockup occurred tonight, and I have attached a tarball containing log files that show many NMI error messages associated with that lockup (but with no reference to the e1000e module this time). @Michel Dänzer: Could you please take a look at these log files and let me know if this is the best place to report the present lockup?
