During SSR data collection period, the processing of hw_error events must wait until SSR data Collected or the timeout before it can proceed. The wake_up_bit function has been added to address the issue where hw_error events could only be processed after the timeout.
The timeout unit has been changed from jiffies to milliseconds (ms).
