Subject: Re: hpsa driver bug crack kernel down!
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
