The spec says the default timeout should be 2ms, but on my machine this doesn't seem to be enough. Sometimes it works, sometimes I get these messages when booting: - SWSCI request timed out - SWSCI request already in progress And my guess is that the "already in progress" message is because the first one is still happening. I did some experiments on my machine (that has CONFIG_HZ=1000) and the wait_for function usually takes 4-6 jiffies to finish, but I've seen up to 9. So increase the timeout to 50ms. We only expect to wait for the actual amount of time the operation takes, so even a huge timeout shouldn't delay us more than what the hardware actually requires.
