I've tested with 2 machines (same problem), with these USB chipsets: machine 1: 0000:00:07.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 10) machine 2: 0000:00:1d.0 USB Controller: Intel Corp. 82801DB (ICH4) USB UHCI #1 (rev 03) I tested with noapic option, same usb crash. Many other people have same problem, maybe not for each upload, but lot of disconnections with same error in logs.. Finally, I have no problem with 2.6.6 kernel or any older kernel (2.6 or 2.4): connection is very stable. Feel free to ask me more for testing. Thanks for any help. I've not subscribed to LKML, so please CC me for any answer. --=20 Cordialement / Best regards Sebastien.
