Subject: hpsa failure with 4.3.0-rc1
Date: Wed, 30 Sep 2015 09:40:50 +0200 [thread overview]
Message-ID: <560B9202.9080703@suse.de> (raw)
Hi all,
trying to boot 4.3.0-rc1 on a system with hpsa results in a swiotlb
failure:
hpsa 0000:22:00.0: Logical aborts not supported
hpsa 0000:22:00.0: HP SSD Smart Path aborts not supported
hpsa 0000:22:00.0: swiotlb buffer is full (sz: 786432 bytes)

4.2.0-rc3 worked fine here.
Needless to say, enabling IOMMU makes the problem go away :-)
Cheers,
Hannes
