I tracked the problem down to the dev_iommu_priv_set call in init_no_remapping_devices. It seems that for one device the dev->iommu member is NULL. An dev_err outputs the device as "pci 0000:00:02.0: DMAR" which is the intel HD 620 graphic adapter in a Lenovo T470s device. The following patch (also attached as intel-iommu.patch) avoids this crash by checking the pointer. diff --git a/drivers/iommu/intel/iommu.c b/drivers/iommu/intel/iommu.c index f8177c59d229..2d285a42db3f 100644 --- a/drivers/iommu/intel/iommu.c +++ b/drivers/iommu/intel/iommu.c @@ -4053,7 +4053,8 @@ static void __init init_no_remapping_devices(void) drhd->ignored = 1; for_each_active_dev_scope(drhd->devices, drhd->devices_cnt, i, dev) - dev_iommu_priv_set(dev, DUMMY_DEVICE_DOMAIN_INFO); + if (dev->iommu) + dev_iommu_priv_set(dev, DUMMY_DEVICE_DOMAIN_INFO); } } } I assume the problem might be related to the following commit introduced in v5.9-rc1: commit 01b9d4e21148c89fdbab3d6b3705f9791314b631 Author: Joerg Roedel Date: Thu Jun 25 15:08:25 2020 +0200 iommu/vt-d: Use dev_iommu_priv_get/set() Remove the use of dev->archdata.iommu and use the private per-device pointer provided by IOMMU core code instead.
