Hi all,
after installation of 5.4.0-47 I also got the impression that the bug was gone
and was happy.
Until now ... I'm getting this type of data corruption with the recent main
focal kernel:
Linux 5.4.0-47-generic #51-Ubuntu SMP Fri Sep 4 19:50:52 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
(relatively fresh Ubuntu 20.04 installation on ZFS after this bug
hopelessly corrupted the old ext4 installation)
Setup:
* remote NFS4 + krb5 ( over Wifi)
* local ZFS
Trigger:
* rsync'ing a large amount of data from ZFS (local) to NFS4 (remote)
Workqueue: rpciod rpc_async_schedule [sunrpc]
RIP:
#1: 0010:kmem_cache_free+0x237/0x2b0
#2: 0010:kmem_cache_alloc+0x7e/0x230
Any idea?
BR, Martin
