Created attachment 303189 [details] dmesg Plugging in an encrypted 2TB SanDisk Extreme 55AE USB 3.0 Type-C SSD causes xHCI controller crash and dropping USB keyboard/mouse and any other USB device connected to the computer. dmesg gets spammed with following errors: [ 3.359704] sd 1:0:0:0: [sda] Sense Key : Data Protect [current] [ 3.359706] sd 1:0:0:0: [sda] Add.

SanDisk Extreme features a drive encryption, it works fine out of the box on Windows or MacOS, it comes with its own read-only UDF partition where unlock.exe resides that can be launched to unlock (decrypt) the drive revealing a ~2TB exFAT partition. Please see attached dmesg log file. If this is not the right subsystem to file the bug let me know. I really would like to get my system booting Linux again since I have the SanDisk Extreme plugged in 24/7. Thanks
Considering there is a page fault, did you already experiment with iommu=pt?
Hi Mario, it did not cross my mind it could be AMD IOMMU related, adding iommu=pt to kernel boot line did in fact make things better! My USB keyboard and mouse are now surviving.
I don't think that proves it to be an AMD IOMMU bug. It could be an ACPI IVRS table (BIOS) issue or a driver bug. Can we see the whole dmesg with iommu=pt? Besides keyboard and mouse, what happens to the other USB device now?
At the moment I'm on my other system with B550 chipset and Ryzen 5800X and have 2TB SanDisk Extreme 55AE plugged into that, however this system was also exhibiting same exact problem as original (B450 motherboard with Ryzen 5600X), so I can give you a dmesg from current B550 system (see attachment), and yes other USB devices or working fine now (I have an USB SD card reader plugged in and Oculus CV1 and they're working fine)

So you can see in there the IO_PAGE_FAULT and decode it using https://www.amd.com/system/files/TechDocs/48882_3.07_PUB.pdf p149/p150. The domain ID 0x18 is selected by the driver, I don't believe it's meaningful in this case. It seems to me that the device/driver for the device is causing the XHCI controller to try to write to address 0xffcf0000.
