------- Comment #7 from [EMAIL PROTECTED] 2008-09-11 16:30 ------- Upgraded to 2.6.27-3-generic (Ubuntu) today and have done additional testing with increased klogd (-c 8) logging I'm attaching two additional outputs: 1. kern.log-with-ehci_hcd: output from a series of dock/undocks until I managed to reproduce the issue. This includes a much more details stack trace, along with an ehci_hcd message: the following is seen after undocking. in addition I'm seeing a lot of USB hub "cannot reset port" messages Sep 11 23:43:50 hanoi kernel: [ 3072.418455] CPU0 attaching NULL sched-domain.

After some time I was unable to reproduce the issue I know very little about the Linux kernel but it seems to me that ehci_hcd is going away on undock. On redock certain interrupts get fired off but ehci_hcd isn't there to handle them -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
