Hi all,
(please cc)
I have now changed my home router and with the new one it
is working without problems at home, and with a few
hickups at work, too.
But still, at work after some time the connection breaks.
I found the following interesting messages in the log:
dmar: DRHD: handling fault status reg 3
dmar: DMAR:[DMA Read] Request device [03:00.0] fault addr fff73000
DMAR:[fault reason 06] PTE Read access is not set
around the time the connection hangs and never comes back.
The mentioned device 03:00.0 is the wlan adapter:
$ lspci -v -s 03:00.0

$
That is with latest git kernel from yesterday.
Any suggestions would be appreciated.
