comment Triggering hardware interrupts by connecting parallel port pins 9 and 10 does not work
Maybe try dump_stack() in e1000_irq_enable() :).

comment Triggering hardware interrupts by connecting parallel port pins 9 and 10 does not work
Surprised me too when I learnt it (and I don't know why it's "the correct way"), but: makelinux.net/ldd3/chp-10-sect-2 "The correct place to call request_irq is when the device is first opened, before the hardware is instructed to generate interrupts. The place to call free_irq is the last time the device is closed, after the hardware is told not to interrupt the processor any more. The disadvantage of this technique is that you need to keep a per-device open count so that you know when interrupts can be disabled."

no, dmesg logs from the start, at least you should see stuff like ACPI and then the PCI bus initialization, which has to happen before driving PCI devices :) ...I can't see what I could have missed.

Maybe we're looking at different things. e1000 enables the irq in e1000_open(), not e1000_probe(). Does the kernel really start the network interface running, without an address, without prompting by userspace? It's at least possible to shut it down, and in that case the irq is disabled.

comment Differences between Debian and Ubuntu
Ubuntu long term support releases are comparable to Debian stable. Actually I think the LTS's are a bit longer than Debian nowadays, and Ubuntu's time-based releases make this nice and predictable.

comment sshfs over mosh tunnel
Ah, sorry. If you did use gnome, I guess you could hack something up in .ssh/config, maybe 'Match host' + ProxyCommand.

comment systemd service can't access user home
@Bratchley that's not what the manpage says. Not sure where the parser source is, but there's at least some display/debug code that calls it ProtectHome, and the struct member is named similarly. github.com/systemd/systemd/blob/master/src/core/execute.c#L2245

comment Why do I get mail when I unplug my adapter?
maybe because of udev timeouts; you're not supposed to run stuff directly from udev if it's going to e.g. sleep for 60 seconds.
