Package: src:linux
Version: 5.2.17-1
Severity: important

Dear Maintainer,

my computer crashes after random times of running (few hours to
several days) with kernels from Debian 8, 9, or 10 (but not 7) when
running as xen dom0, always with netdev watchdog timeout on transmit
queue.

It is a home server running debian since 2009, rock solid until Debian
7 with kernel 3.16.x, random crashes with kernels 4.9, 4.19, and 5.2,
always with xen. Different network adapters, different actual failures
afterwards. Sometimes only the network adapter resets, sometimes sata
devices fail, but operate normal again after reboot. memtest does not
show any errors.

Usually I have to reboot this host and restart the virtual machines
running on it. I dist-upgraded from Debian 7 to 8, and collected
console output over the last year for Debian 9 and (not yet released)
with different kernel versions. The first line of the log after "cut
here" is always the same (although with different network adapters):

  NETDEV WATCHDOG: *** (***): transmit queue 0 timed out

The call trace always shows things like xen and irq, e.g.:

Although this is annoying and I considered buying new hardware, I'm
confident this could be solved, if someone assists me. I offer to
test new kernels and could also compile those by myself. I will attach
my logfiles in further responses to this report.

Kind regards
Alex
