Description

When doing a large number of suspend/resume cycles (tens of thousands), we occasionally see a kernel crash upon resume.

After filtering out the kernel crashes due to actual kernel bugs, we are left with a number of crashes which appear due to hardware problems, specifically memory corruption.

This seems to favor certain laptops, and is not seen on all machines. There is a special version of OFW (q2d01a) which implements a comparison of memory before and after the resume. It may be used to test specifically for this case.

Trac #4459 is a duplicate of this, where the corruption was caught and reported by q2d01a. It includes kernel logs from the crashing laptop.

Changed 4 years ago by wad

  • status changed from new to closed
  • next_action set to never set
  • resolution set to duplicate

This was almost certainly a side effect of #1835.

Closing out as a duplicate (and fixed!)
