MacBook Pro M1 crash while Raid drive mounting (Softraid 6.0.5 and Mac OS 11.6)

Still getting a Kernel Panic with my new 2021 MacBook Pro 16" M1 Max, attached is the report.

@softraid-support howdy. I just installed the new beta driver, but it doesn't appear to have fixed anything. I can still pull a drive to sidestep the problem, though.

@craignos 

this is the Thunderbolt issue we are working with Apple on. We are waiting for a solution.

@bnsrx 
We did not make any change that would affect this issue in the new beta. It fixed a couple other issues.

@softraid-support Somehow, 6.2.1 b7 seems to have done some miracles for me so far... been mounting my Thunderbolt 4bay RAID5 the last 4 times with no crashes... (MacOS 10.12.1 on M1Max).

QUESTION: my Thunderbay 4 goes to sleep quite often even if I have set my drives NOT to go to sleep through sys prefs, any way to change that? thanks.

Cheers

@craignos 

Thanks for the feedback, but the changes we have made so far should have little impact on the Thunderbolt bus crash. interesting.

MacOS controls sleep. All you can do is disable put drives to sleep and set display sleep to "never".

@softraid-support yes, and that's the thing, it still goes to sleep (see attachment)

@craignos 

Set the display sleep to never. that should fix this.

MacOS controls all aspects of sleep. the SoftRAID driver has no influence on sleep settings.

Whatever changes you made in 6.2.1 b9 has totally fixed my machine! I can now restart without having the crash. Amazing. Thank you!!!

this was a RAID 5 volume crashing at startup? or was it crashing from Time Machine?

@softraid-support 

Yes this was a raid 5 crashing on startup, so I would have to remove a drive to get it to mount, and then put it back in after. much better now, thanks!

@softraid-support HI there Softraid support team, just wanted to report that I'm still able to mount my Thunderbay 4 RAID5 with no issues since SoftRAID 6.2.1 b7, running Mac OS Monterrey 12.1 on a 16" MacBook Pro M1 Max with the latest Softraid beta11.

(going to update to 12.2)

Not sure what happened since then but it's workings far. If you need any hardware/software information, let me know.

@softraid-support hi there - I'm still having a kernel panic on startup if I boot without removing a drive first. Currently running 6.2.1 public release. Do you know if the issue has been resolved, or if you're still waiting on something to make it work?

@bnsrx 

We are still waiting for a result from Apple engineering.

We have learned one new solution, which is using 64k stripe unit size on RAID 5 (have to delete/recreate your volume to do this)

There is an engineer assigned, but no results yet.

Thanks for the update, much appreciated.
