I've recompiled pwc adding some extra logging and this is the output

The first error is

kernel: pwc: Failed to set LED on/off time; error -110 .    <<<<<<<<<<<<<< this is the first error

Does anybody know what -110 means?

Moreover, these 2 lines DON'T happen on a x86

kernel: pwc: probe() called [046D 08B2], if 1
kernel: pwc: probe() called [046D 08B2], if 2

any idea?

Thanks
