Looks like a spinlock issue in the NFS kernel server code. I'll attach the output of dmesg while the machine was dying in a file called "spinlock". A shame because while it was running, the performance of 5.8 was astounding. Only the NFS servers seem to get ill, the client machines seem to run fine on 5.8 so far at least. -- You are receiving this mail because: You are the assignee for the bug.
