Tested with default fwts s3 options (30s) with --s3-multiple=30 on 202503-36448. The fluctuation of sleep duration improved significantly (~1 second), and met fwts' criteria.

[ 245.081957] Timekeeping suspended for 98.914 seconds [ 351.082704] Timekeeping suspended for 3.017 seconds [ 457.084662] Timekeeping suspended for 98.893 seconds [ 564.087162] Timekeeping suspended for 4.024 seconds [Fix] The root cause is from intel-ish-hid driver that fails to respond and blocks the suspend process for around 90 seconds totally. Intel provides a patch to fix this issue. [Test] Use fwts to run to sleep test and then check the Timekeeping suspended should be around 60. sudo fwts s3 --s3-multiple=30 [Where problems could occur] The fix increase the resume timeout from 50ms to 300ms, it should not introduce any issue.
