We test it with Linux kernel 5.1.0-rc4. The system hits the following error and makes system hang up: Apr 09 11:28:57 endless kernel: AMD-Vi: Completion-Wait loop timed out Apr 09 11:28:57 endless kernel: iwlwifi 0000:03:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=3D0x0000 address=3D0xff814000 flags=3D0x0050] The worst case is the disk's block may be disrupted, then we have to re-ins= tall the system if it cannot be recovered by fsck. If we blacklist the amdgpu module, then system will not hit the error. But system has no GUI, and only shows console. If iommu=3Dsoft is appended to the boot command, system works fine. --=20 You are receiving this mail because: You are the assignee for the bug.= --15547882610.bBF5b01f.15623 Date: Tue, 9 Apr 2019 05:37:41 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://bugs.freedesktop.org/ Auto-Submitted: auto-generated
