Dave in comment #10 you said "load on the ARM during transfers (my hunch is, if anything is affected, it'll be the latter - I vaguely recall forum posts about improvements on the ARM load during large USB transactions)." Were the systems checked for load during the transfer tests?
Additionally, would it be worthwhile to test different versions of USB media? I'd really hate to be caught off guard by something. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1852510 Title: IO errors when writing large amounts of data to USB storage in eoan on RPI Status in linux-raspi2 package in Ubuntu: New Status in linux-raspi2 source package in Eoan: In Progress Bug description: Kernel tested: Linux ubuntu 5.3.0-1012-raspi2 #14-Ubuntu SMP Mon Nov 11 10:08:39 UTC 2019 armv7l armv7l armv7l GNU/Linux I've only been able to reproduce this with the armhf kernel and on the following devices: RPI3B+ RPI3B RPI2 At the moment, it does not appear that arm64 is affected, nor are RPI3A+ and RPI4 (at least not the 2GB version) Steps to reproduce: - Insert and mount a USB storage device - cp a large file to it (300-600MB recommended - smaller files will sometimes not trigger it) - sync After running the sync, a lot of IO errors will show up in dmesg like: [ 176.129299] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [ 176.129326] sd 0:0:0:0: [sda] tag#0 CDB: Write(10) 2a 00 00 2e 24 b0 00 00 f0 00 [ 176.129349] blk_update_request: I/O error, dev sda, sector 3024048 op 0x1:(WRITE) flags 0x4000 phys_seg 15 prio class 0 [ 176.883968] usb 1-1.1.2: reset high-speed USB device number 8 using dwc_otg [ 177.079960] usb 1-1.1.2: reset high-speed USB device number 8 using dwc_otg It eventually finishes, and if you unmount/remount the device, the checksum will be different from the original file.
