Maybe we can figure out what's common between our systems since I
imagine if everyone were getting this error then this bug would be
getting more attention.
I'll also note this started for me with 5.15. 5.13 and earlier did not
exhibit this error. System seems to run fine though. No noticeable

I'll also add that this problem is still present in kernel 5.8 (no
matter if you use "modesetting" or "intel" driver for the Braswell GPU.

I'd like to share a slightly improved workaround on this for those still
dealing with the issue. The core problem seems to be that the mouse
cursor can go into a negative X position by one pixel when moved to the
far left of the screen. With either the now obsolete intel proprietary

I did not apply the patch in #13, but I did try disabling highdma with
ethtool (essentially what the patch makes permanent) and that had no
effect for me (at least not on the kernel I was using at the time). I
did try the patch in #40 and that had no effect for me either. The only
thing I've found
I'll also add that though I had previously tried iommu=soft with no
luck, trying iommu=pt as suggested by chithanh in post 70 does seem to
workaround the issue successfully. I'm not sure as to why that would be
the case as this is neither a VM nor a VM host, but since adding the

I can confirm that the problem is present with both the intel and the
modesetting driver on Braswell systems. The exact symptoms differ for
each, but in both cases it is triggered when the mouse touches the left
limit of the screen. With modesetting, it seems to "stick" until you
move the mouse awa
Public bug reported:
When the defaults are left in the "Workspaces" preferences, everything
functions as expected. But when the options are reversed from the
defaults, the result is that the icon for the most recently opened app

Yes, removing and re-adding the modules as you describe does at least
recover eno1 without rebooting. Still, hardly a solution for what was
intended to be a headless Plex server. This happens every time I start
an mpeg2 tv stream through my plex box which is only about a 20mbps
load.
Also, on the last crash, I caught it while it was happening and RX/TX
errors and collisions all went through the roof right before it went
"no-carrier".

Confirmed that this is still an issue on 18.04.1. I have an HP 705 G1
with the Broadcom 5762. In my case it's a Plex server. Whenever I try to

recover is to reboot. I've tried disabling highdma, tso and gso using
