Some additional notes from testing last night (more or less blindly after a load of googling for dwc_otg errors and mitigations):
* Adding dwc_otg.speed=1 (limiting the driver speed to Full Speed USB1.1), fixes the mass-storage issue, but breaks compatibility with most keyboards. So, not terribly useful as a work-around but may be helpful in debugging? * All other attempts either yielded no difference or just broke things further; did have a quick play with the various DMA options (e.g. dma_enable) on the basis of your notes above but managed no improvement. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852510 Title: IO errors when writing large amounts of data to USB storage in eoan on RPI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1852510/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
