Unfortunately I have exactly the same problem since I upgraded to Edgy. I could go back to Dapper but I think that is ridiculous... An upgrade should be more stable than the previous version and I don't understand how this could happen! I would never go back to an old version of Ubuntu, if there are no other options left I will switch to another distro (Fedora has no problems copying large files).
I'm still having a few more problems with Edgy but I doubt their related. It's nice to see that the 2.6.12 version of the problem has such a high priority, maybe the 2.6.17 version could also get a high priority!? -- usb flash memory hangs after copying few MB https://launchpad.net/bugs/17881 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
