Hi Solene, I’m not sure if this is related but I’m seeing console freezes on my 
i386 laptop.

I’m not using X, just the console. And I believe I’ve experienced these freezes 
with and without drm enabled.

The symptoms for me are the keyboard stops working for certain letters. And 
then the console freezes completely shortly after that.

I’m able to recover from this by switching to a different console and then 
doing “kill -9” on the stuck ksh process.

When your system freezes, are you able to switch to a different console? Or can 
you still ssh into it?

I’m not sure if it’s a hardware issue on my end or some bug and wasn’t exactly 
sure how to debug this as I can’t reproduce easily.

Things I tried:
1) using historical kernels, but all the kernels I tried so far don’t solve the 
problem.

2) ktracing the ksh processes on each console to see if there’s something 
obvious that triggers the problem. I’m working on getting some traces but I 
haven’t managed so far because the freezes are so random.

Things I’m thinking of trying:

1) installing a different OS to check if it’s a hardware problem.

2) reinstalling 6.4 and 6.5 to see if I see the same problem. If yes then 
likely a hardware problem because I used those releases in the past without any 
issues.
