Subject: Re: 5.10 regression, many XHCI swiotlb buffer is full / DMAR: Device bounce map failed errors on thunderbolt connected XHCI controller
Date: Mon, 23 Nov 2020 15:49:09 +0100	[thread overview]
Message-ID: <be031d15-201f-0e5c-8b0f-be030077141f@redhat.com> (raw)
In-Reply-To: <b046dd04-ac4f-3c69-0602-af810fb1b365@redhat.com>

Hi,

+Cc Christoph Hellwig <hch@lst.de>

Christoph, this is still an issue, so I've been looking around a bit and think this
might have something to do with the dma-mapping-5.10 changes.

Do you have any suggestions to debug this, or is it time to do a git bisect
on this before 5.10 ships with regression?

Regards,

Hans
