Package: src:linux
Version: 1:6.6.31-1+rpt1
Severity: normal
File: linux-image-6.6
X-Debbugs-Cc: pronoiac+deb...@gmail.com
Dear Maintainer,
Short version:
I was benchmarking some compressors on Debian on a Raspberry Pi, piping to and
from a network share on a NAS, and found that some consistently had issues
writing to my NAS.
Specifically: lzop, pigz (parallel gzip), and pbzip2 (parallel bzip2).
This seems dependent on kernel version:
Debian 11, bullseye, kernel 6.1.21, was ok.
Debian 12, bookworm, kernel versions 6.6.20 and 6.6.31, were impacted.
Compiling and running a mainline kernel 6.1.21 on bookworm avoided the issue. I
don’t think Debian patches are at fault.
There's over a year between those kernel releases. Bisecting won’t be quick,
but it is doable.
More details:
The Pi and NAS are directly connected by Gigabit Ethernet. Both sides are using
self-assigned IP addresses.
The files in question are file systems, about 250 GiB.
Compression seems to work, without complaint; decompression crashes the
process, usually within the first gig of the compressed file. It looks like the
compressed files are corrupt.
Trying decompression during compression gets further along than it does after
compression finishes; this might point toward something with writes and caches.
This is a Raspberry Pi 4, with 4 GiB RAM.
I could see "grave" severity for this, as there's potential data loss.
Previously:
* bug #1079394 looked similar, but I've already tested kernel 6.6 and seen the
issue, so it's not the same exact bug.
