I work for Oracle, and this problem is preventing me from being able to copy large patch bundles, used during customer installs. In addition, I can attach the drives to an old laptop running bare-metal OL7.2, and it works just fine.no resets, hangs, or slow I/Os, during the 'dd' (or file copies). The seagate is formatted as NTFS and the WD is Linux EXT4. It's happening on two different USB drives: Seagate 2TB and Western Digital 2TB. OL and Ubuntu updates don't help, either. I've attempted to workaround this with the new test build 6.0.0 RC1, and it didn't help. ![]() ![]() The OL system log shows the resets and I/O errors as:ĭec 10 15:55:28 jdnissen-lobi7 kernel: usb 2-1: reset SuperSpeed USB device number 2 using xhci_hcdĭec 10 15:55:38 jdnissen-lobi7 kernel: usb 2-1: reset SuperSpeed USB device number 2 using xhci_hcdĭec 10 15:55:44 jdnissen-lobi7 systemd: Got automount request for /proc/sys/fs/binfmt_misc, triggered by 1858 (cma)ĭec 10 15:55:44 jdnissen-lobi7 systemd: Mounting Arbitrary Executable File Formats File System.ĭec 10 15:55:45 jdnissen-lobi7 systemd: Mounted Arbitrary Executable File Formats File System.ĭec 10 15:55:46 jdnissen-lobi7 kernel: EXT4-fs (dm-3): Delayed block allocation failed for inode 12 at logical offset 546816 with max blocks 2048 with error 5ĭec 10 15:55:46 jdnissen-lobi7 kernel: EXT4-fs (dm-3): This should not happen!!

I'm able to replicate the problem, very quickly, by running the following: Experiencing USB reset and hangs on Virtualbox 5.2.22 on Macbook Pro 2017 10.13.6, on Oracle Linux 7.5 and Ubuntu 18.04 VMs. ![]()
