Hello,
ISSUE: Can no longer mount NFS server(5.13) share.
WORKAROUND: Reverting back to the 5.13-rc7 kernel for the NFS server, all
clients can then mount the share.
Kernel 5.13 vs. 5.13-rc7 for x86_64
With Kernel 5.13-rc7:
## mount is successful (from multiple clients, phone, tv, other Linux
client)
# mount 192.168.1.2:/r1 /r1
#
With Kernel 5.13 (hangs from multiple clients, phone, tv, other Linux
client)
## mount hangs:
# mount 192.168.1.2:/r1 /r1
(strace output where it is hanging)
...
