Bug#939697: "b44: swiotlb buffer is full" kernel log spam on Dell Inspiron 6400 wired NIC with kernel 5.2
Package: src:linux
Version: 5.2.9-2~bpo10+1
Severity: normal
Recently I checked out the latest kernel packages from Backports for my Dell
Inspiron 6400 laptop, which ships with the following Broadcom wired NIC:
03:00.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM4401-B0 100Base-
TX (rev 02)
I've never had problems with this NIC, been using it with kernels as old as
2.6.9. It works just fine with the default Debian Stable kernel (which is 4.19
on Buster). But with 5.2, I get my kernel log spammed with this every time
there is network traffic on the wired NIC (I don't use wireless on this
system):

I even get a stacktrace during boot (most likely during DHCP negotiation?)

I'm not alone: another user on another Inspiron 6400 is experimenting the exact
same issue, but on Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1821564
...so it looks like it's a kernel regression?
