iaStorA.sys causing system to crash on entering sleep

HP Recommended
Microsoft Windows 10 (64-bit)

Since about 15 Nov 2019, this HPE 490T has been crashing and powering off when it power management puts it in sleep mode (upgrading to Windows 10 had the pleasant side effect of making sleep work finally ... until mid Nov).  I've looked at a few crash dumps since then & it looks like the Intel RST (Rapid Storage Technology) driver iaStorA.sys is the culprit.


device manager says this driver is 12.x something & dated 2013.  There are much newer versions of this driver.  I recall vaguely I had some kind of problem with this when I upgraded to WIndows 10 (maybe I or the upgrade tried to update the driver, & it didn't work right; I did something to roll back I think).   BIOS issue?

HP & Intel diagnostics don't offer a driver upgrade.   HP doesn't recognize this system running Windows 10 anyway.


It would be nice to get power "sleep" to work again (saves $$) but I could live without it.  Don't think I could work without functioning SATA drives, tho, & if the driver is not co-existing with Windows 10 very well, that will be trouble eventually.


Any ideas?
