I have a laptop that suspends and resumes fine. Soeren's patch to properly reset the hardware after the ATAng import fixed the problem where resuming would hang in ata0 reset with the hard drive light on. Sometime in the last month or two, the ATA reset phase of resume has begun hanging again with the drive light on and I can't break to the debugger. The interesting data point is that if I suspend/resume in single user mode, it works fine, including the reset. But in multi-user mode, it hangs. I'm trying to disable various services to see if any of them triggers the hang. Has anyone else seen this regression? -Nate
