Heya!
I've been running into following issue with recent kernels fairly often
when waking up Dell Latitude D610 laptop from suspend:

Any ideas where to look further?

if (WARN_ON(usermodehelper_is_disabled())) {
dev_err(device, "firmware: %s will not be loaded\n", name);
retval = -EBUSY;
goto out;
}
The usermodehelper gets enabled by suspend_finish() in
kernel/power/suspend.c, so something is waking up the ipw driver from
userspace before the kernel has completed waking up. Maybe make
whatever that thing is that pokes ipw wait a second?
