Hi all, Today we've seen a kernel panic that looks like related to delegations and laundromat ... [1388051.959652] Call Trace: [1388051.959984] unhash_delegation_locked+0x39/0xa0 [nfsd] [1388051.960631] laundromat_main+0x235/0x5a0 [nfsd] [1388051.961234] process_one_work+0x1fd/0x3f0 [1388051.961803] worker_thread+0x34/0x410 [1388051.962281] kthread+0x121/0x140 [1388051.962698] ? process_one_work+0x3f0/0x3f0 [1388051.963210] ? kthread_park+0xb0/0xb0 [1388051.963690] ret_from_fork+0x22/0x40 .... In the link below you'll find what has been captured from the console. https://pastebin.com/raw/CdpMfUAK I couldn't really find any reference to this in the mailing list history so I assume we might have hit a bug that is unknown so far.
