Description Martin Lorenz 2005-03-08 00:50:32 UTC
Distribution: After upgrade to 2.6.11 (from 2.6.9) my USB-port needs
unloading/reloading of ehci/ohci modules to gut back to work after S3

Hardware Environment: SHARP PC-MM10
Software Environment: debian SID
Problem Description: Since I compiled 2.6.11 (using the config from 2.6.9 plus
the extra options make asked me :-) the usb subsystem no longer works after
suspending to ram. unloading and reloading ehci and ohci modules fixes it....

Steps to reproduce: boot

Comment 5 Martin Lorenz 2005-03-08 23:45:49 UTC
Just discovered that the described behaviour is not always reproducible
I did not change anything in my suspend/resume process nor in my kernel or any
other part of the system but lately it worked.

on the other hand yesterday evening I lost all ACPI events after one
suspend/resume cycle...
I had similar problems in early 2.6-rc and 2.6 kernels (until 2.6.3 I think)

Comment 6 Andrew Morton 2005-05-25 15:31:54 UTC
Can you please retest 2.6.12-rc5 and provide an update?
Comment 7 Martin Lorenz 2005-05-26 12:02:11 UTC
seems to work again

but a new strange thing strikes me: the udev rule i configured for my memory-stick 
no longer reacts on the serial number of the stick

i had to rwrite the rule to take the vendor name instead.
it seems, that some fields no longer are reported to hotplug ...

Comment 8 Len Brown 2005-08-17 10:41:10 UTC
thanks for re-testing. please open a new bugzilla on
the memory stick issue if that is still a problem.
