Hi, i'm not sure if this is same bug or not but symptom is similar. I managed to get it working but wasn't sure which actually made it worked but now it stopped working again. I have a Dell Latitude E7250 and i boot into the 18.04 based elementaryOS from usb, so after resume the filesystem becomes read-only and i can't save the dmesg output.
What i've done 1. Added #32 workaround 2. Added udev rules to set power/control for my usb device to auto. 3. Enabled USB Powershare in the bios (not sure this was the one but the issue was gone after i set this after the above 2, 2 days later issue came back) 4. Set usbcore.autosuspend=-1 in grub 5. Upgrade to 4.19LTS Symptom: 1. On AC: suspend/resume works perfectly 2. On Battery: if resume from suspend while AC succeded, the second resume while on Battery works but the subsequent suspend/resume fails in system read-only again. 3. On Battery: suspend/resume does not work resulting in system read-only. I've been trying to reproduce my earlier success but to no avail. Even a fresh install, the system will become read-only Right now, suspend/resume only works on AC which leads me to suspect the USB hub/device is making this fail. p/s sorry if i'm not following the right bug reporting etiquettes. i've done a lot of searching and tried multiple solutions but still can't fix this. Any help would be greatly appreciated and i will provide any help i can. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1291969 Title: No usb on resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1291969/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
