http://bugzilla.kernel.org/show_bug.cgi?id=7180
Summary: aic94xx driver locks up on IBM x366 with Calgary IOMMU
enabled
Kernel Version: 2.6.18
Status: NEW
Severity: normal
Owner: djwong@us.ibm.com
Submitter: djwong@us.ibm.com
CC: alexisb@us.ibm.com
Most recent kernel where this bug did not occur: 2.6.17
Distribution: Ubuntu 6.06
Hardware Environment: IBM x366, 4x 3.16GHz Xeon, 8G RAM, aic94xx SAS controller,
6x 36G SAS disks, Calgary IOMMU
Software Environment: netbooted Ubuntu mutant.
Problem Description: aic94xx driver NMIs the system if calgary iommu is enabled.
Steps to reproduce:
1. Clone linux-2.6 and add in scsi-misc, scsi-rc-fixes and aic94xx from
git.kernel.org.
2. Build a netbootable "allmodconfig" kernel with attached config file.
3. Calgary IOMMU code activates
4. Subsequent loading of the aic94xx driver causes the service processor to log
a PCI SERR with a split completion timeout, followed by an NMI, followed by a
reboot.
Note that disabling the Calgary IOMMU for the bus that the SAS controller is
connected to (either via kconfig or iommu=none or calgary=disable=1) will make
the problem go away.
