Bug ID: 208807
Summary: Problem with NFS kernel server code
Product: Networking
Version: 2.5
Kernel Version: 5.8.0
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
Assignee: stephen@networkplumber.org

Output of dmesg while machine was dying
After about an hour and a half of operating on 5.8.0, one of our NFS servers
began to slow and basically ground to a halt. 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.

Commented, but I guess it should really be reassigned to nfsd, I'm not
sure how.
