Thanks for the debugging info, that was really helpful. We had a very nasty story here. In 4.18, hda tries to register to the i915 module, but doesn't wait if the module is not loadable. In 4.19.12 (used in alpha5), it was made to wait for 10s. It was noticed at the time that audio could take a lot of time to initialize, thus the espeakup wait was increased to 30s for good measure. And then in 4.19.37 (used in rc), the wait was increased to 60s! 30s is thus not enough now. I'll see with linux packaging people to include the 915 module for the 10.1 dot release. So to summarize: all hardware which have HDA-based cards will have the issue. Samuel
