Please try that, it will be very useful to know.

I haven't set "submit IO's one at a time" but I can try that and report back, if helpful.

What kind of IO activity is going on? Small random files?

If you set the SoftRAID disk Preferences, to "submit IO's one at a time" do the panics still happen?

thanks!

These are two Thunderbay 8's?

Daisy chained? or on separate buses?

Nothing stands out at first look

Unfortunately, every week or so, my Mac Pro (2020) shuts down due to a kernel panic when running time-consuming queries. Per the crash report, the trace points to the SoftRaid kernel extension (see below). Is this a bug in the driver? Or what can I do to avoid this problem?
