Re: IO Problems (USB) seem to hang on Boot (AMD64)
So, I'm still having serious issues with this thing: I used the following procedure to update the grub-bootloader, from Linux Mint: mount /dev/sda6 /mnt sudo mount --bind /dev/ /mnt/dev sudo mount --bind /proc/ /mnt/proc sudo mount --bind /sys /mnt/sys cp /etc/resolv.conf /mnt/etc/resolav.conf sudo chroot /mnt I then changed the line: GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="iommu=soft" and ran update-grub. I do have IOMMU disabled, and I did the same thing to my Linux Mint Intallation, and now I can run *that* without IOMMU support enabled. I reloaded optimized defaults on the UEFI, and I saw my change in GRUB2. Now, I consistently get another error message when trying to boot. [3.(something)] [drm] :01:00.0: PMC unhandled INTR 0x4400 The error messages from recovery mode may be slightly more insightful: [3.(something)] [drm] nouveau :01:00.0: Register 0x00680520 not found in PLL limits table [3.(something)] [drm] Supports Vblank Timestamp Caching Rev 1 (10.10.2010) [3.(something)] [drm] No driver support for vblank timestamp query. [3.(something)] [drm] nouveau :01:00.0 voltage table 0x50 Unknown [3.(something)] [drm] nouveau :01:00.0: Register 0x not found in PLL limits table [3.(something)] [drm] nouveau :01:00.0: Failed to determine boot perflvl [3.(something)] [drm] nouveau :01:00.0: Pixel Clock Comparison table not found Otherwise this is a 100% squeeky clean fresh install of Debian. A great column of the item listed above this list precedes it. Now I have no idea what is wrong Thanks Again, A user
IO Problems (USB) seem to hang on Boot (AMD64)
To all Glorious Saviors: Installation goes smooth. When asked, during installation, I install device-specific drivers. For the record, this is the AMD64 distribution. So, whenever my IOMMU Contoller is enabled on the UEFI of the motherboard, I get this error: [ 1.669503] AMD-Vi: Event Logged [IO_PAGE_FAULT device=2:00.0 domain=0x0017 address=0xbe9f9880 flags=0x0010] filling my screen. When IOMMU is disabled, I get along the lines of [2 OR 3 OR 4 OR 5 . (randomnumber)]usb 3-5 device descriptor read/64, error -32. Somehow, I've also generated an error along the lines of: [ 20.979743] nouveau :01:00.0: PMC unhandled INTR 0x4400 The only success I've had in dealing with this is when I tried to use clonezilla, it was having serious problems. I was able to get *it* working (the Ubuntu-based version) with the following command in the boot parameters: "quiet splash usbcore.old_scheme_first=1". However, no such luck with Debian The install process is fine. I just *can't* get it to boot. Sincerely, A User
