Comment 3 Chris Wilson 2019-04-04 18:31:26 UTC

"failed to allocate THP, finishing test early" is a debug message (technically an info).

The root cause here is likely to be the memory corruption we see around icl.

Comment 4 CI Bug Log 2019-04-05 05:20:02 UTC

Comment 5 Francesco Balestrieri 2019-04-08 10:48:21 UTC

Another one that we'll keep observing, but no immediate action to be taken. I suggest moving to "high".

Comment 6 Jani Saarinen 2019-04-11 06:42:14 UTC

BIOS was updated last week on this U2 system.

Comment 7 Lakshmi 2019-04-11 06:49:11 UTC

Yes, we we keep monitoring this issue, since it's a BAT failure we should see more often if it appears again. Setting the priority to high. 

The worst case would be that user can not use hugepages. 
@Francesco, What would be the impact hugepages doesn't work?

Comment 8 Chris Wilson 2019-04-11 06:53:06 UTC

The bug is nothing to do with hugepages; it's the general memcorruption bug.

Comment 9 Francesco Balestrieri 2019-04-11 07:44:57 UTC

Lakshmi, this appears to have the same root cause as Bug 110329

Comment 10 Jani Saarinen 2019-04-22 12:19:59 UTC

Should we dup this then?

Comment 11 Jani Saarinen 2019-04-22 12:22:42 UTC

Not seen after BIOS update.

Comment 12 Francesco Balestrieri 2019-06-03 05:25:25 UTC

Still not seen after two months. Closing.
