The device also worked fine on older kernels (and Windows/XP). A Linux tools to create USB power summaries would be helpful here. I have a suspect that I want to verify: Some USB device (an external harddisk) execceded the allowed maximum current and put the USB chip into some state that the kernel cannot deal with (I did reboot Linux several times, but did not power-cycle the machine during my tests). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

And running Windows after the problems were persistent with openSUSE, no problem occurred.

The failing application in turn seems to make the USB subsystem inoperable. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

An application can seg fault with or without kernel involvement. If there is kernel involvement, there will _always_ be a log message. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If you had carefully read through the reports, and looked at the attachment, counted in the human/user factor, then this would have been clear. Greg: the reason why this bug interests me is because i am seeing something similar on SB600; sadly on an ubuntu (nokia/meego has everything prefabricated for ubuntu, sadly -- i had to part with a highly reliable 11.1 installation). I am constantly plugging and unplugging a nokia proto these days, and after a while i hit similar messages on a 2.6.35 (after an ubuntu provided update -- Ulrich has a 2.6.34.7), while i never saw them on 2.6.32 (ubuntu's -27). I know this is a huge range, but given my available time, i cannot narrow it down further right now. I am sure that there are plenty of sb600/700 systems still sitting around in at least the nue office. One more symptom; after throwing out -110s, plugging in new devices makes nothing new pop up, and a reboot/hibernation is necessary. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What caused me to add info now is that i feel that this bugzilla entry needs some help; a lot of time has been lost in confusion. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
