Subject: Re: hpsa driver bug crack kernel down!
Date: Tue, 15 Apr 2014 00:19:53 +0800	[thread overview]
Message-ID: <534C0AA9.5080909@linux.intel.com> (raw)
In-Reply-To: <1397490358.31076.6.camel@buesod1.americas.hpqcorp.net>

Hi Davidlohr,
	Thanks for providing the DMAR table. According to the DMAR
table, one bug in the iommu driver fails to handle this entry:
[1D2h 0466   1]      Device Scope Entry Type : 01
[1D3h 0467   1]                 Entry Length : 0A
[1D4h 0468   2]                     Reserved : 0000
[1D6h 0470   1]               Enumeration ID : 00
[1D7h 0471   1]               PCI Bus Number : 00
[1D8h 0472   2]                     PCI Path : 1C,04
[1DAh 0474   2]                     PCI Path : 00,02

	And the patch sent out by me should fix this bug. Could you please help
to have a try?
Thanks!
Gerry
