Bug#1004070: linux-image-4.19.0-18-amd64: kernel crashes when accessing files via nfs
Package: src:linux
Version: 4.19.208-1
Severity: important
Dear Maintainer,
after dist-upgrading to debian 10 the kernel crashes when accessing
files on nfs mounted filesystems. The bug can be reproduced by writing
between 100 and 1000 files á 50MByte to the mounted filesystem. The system
crashes completely, i.e. you cannot ping and ssh is dead. I have
to powercycle via ipmi to come back.
The bug is not there when I boot the previous 4.9.0-16-amd64 kernel.
This is a headless system with 4 nvidia gpus running with the proprietary
nvidia driver version 470.82.01. I do not think that this is related as
the bug happens even when nothing is happening on the gpus. The bios is from 2015 but I
load the intel-microcode.
Looking upstream, maybe this bug is related to
Bug 203827 - NFS v4.1 and v4.2 still unstable - https://bugzilla.kernel.org/show_bug.cgi?id=203827
Bug 200145 - kernel: FS-Cache: Duplicate cookie detected - https://bugzilla.kernel.org/show_bug.cgi?id=200145
Regards
Friedrich
I can reproduce the bug with the following script:
=== killer script
#! /bin/bash -xe
cnt=1
for (( ; ; ))
do
echo "Run: $cnt"
((cnt++))
dd if=/dev/urandom of=~/sf bs=1M count=50
rm ~/sf
done
