Interestingly anyone knows what is that spammy 'testing the buffer' message? Google didn't really help.
It's been already addressed, see bug 1168664 -- You are receiving this mail because: You are on the CC list for the bug.

Also should I boot it with "iommu=off" with respect to the error in the dmesg output?
You mean that or something else? [ 1.522731] pci 0000:00:00.2: AMD-Vi: Unable to read/write to IOMMU perf counter.

Yes this, just asking as it is shown as 'red' in the output but I honestly dunno if disabling it would not bite me more. -- You are receiving this mail because: You are on the CC list for the bug.

This message is harmless, it just means that there is no support for IOMMU performance counters on this system. But the IOMMU is otherwise okay and can be used. -- You are receiving this mail because: You are on the CC list for the bug.

Btw, is that box yours or can I get it for experimenting? As in, try kernels and some patches...
Yeah it is SUSE provided lappy. Just limiting we ain't in the office and I need it kinda to connect to the HW in the office right now. Whenever we can go back to the office I can get it to your desk and you can have fun with it tho :-). -- You are receiving this mail because: You are on the CC list for the bug.

Anything new here?
Tomas, could you provide Boris with the access to the laptop?
Well as we are stuck at home I am rather fond of having working machine :) BUT there are at least 7 same laptops in our prg storage, so I suppose we can take one of those. Also removing the blacklist shows the trace on latest in TW still. -- You are receiving this mail because: You are on the CC list for the bug.
