Hi list,
Please CC: me since I am not subscribed to the list.
I am using Linux (uptodate Debian sid) on an 12" iBook (mid 2005
model). I am having some problems with usb moduleswhen I resume from
suspend-to-disk.
If the usb modules are loaded, I get a kernel oops and the system is
frozen. However, when I unload the usb modules before suspending, the
system resumes normally. But when I try to reload the modules
(ehci_hcd or ohci_hcd), I get again a kernel oops,and a "Bus error"
message.
I am using Debian kernel 2.6.18-4, but I get the same behaviour with
debian kernel 2.6.20 from experimental, and various self-compiled
kernels (2.6.21-rc5, 2.6.20, 2.6.18). In all of these kernels all
selected options for USB are compiled as modules when possible.
What is strange is that I cannot remove usbcore with these kernels
(module in use), although this was possible with 2.6.16.
I attach here an piece of my syslog showing a suspend process,
followed by a resume terminating by an oops.
Do you known how to solve that ? Do you need any more information ?
you can also find a picture of my screen after (another) oops here
