I've only recently traced the issue to the iommu kernel option. This device has been unstable since I bought it and I pull it out occasionally to see if the driver issues have been addressed.
I'm afraid that the test system I'm using is currently unavailable. I'll post an update when I have a chance for fresh testing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810239 Title: amd_iommu conflict with Marvell 88SE9230 SATA Controller To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1810239/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
