Ok, we should take this upstream. Please send a summary of symptoms to [email protected], cc-ing [email protected] and either me or this bug log so we can track it. Be sure to mention: - steps to reproduce the bug - symptoms, how they compare to the expected result, and how that indicates a bug - which kernel versions you have tested, and results for each - which USB devices you have tried, and how the results vary with choice of gadget, if at all - full "dmesg" output from booting an affected kernel and reproducing the bug, as an attachment - a relevant snippet of "lspci -v" output describing the USB adaptor - a link to http://bugs.debian.org/649937 for the full story Hopefully others on the list can help figure out whether this problem is hardware-specific and if so, what the relevant variables are, or if it is a problem with USB support in general on the sparc. And maybe to work towards a fix. ;-) Thanks for your work, and hope that helps, Jonathan -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
