Various errors when running Steam-Games from ZFS-Pool/Dataset

[besterino]

Win11 Pro for Workstations (German)
24H2 (Build 26100.3194)
OpenZFSOnWindows-debug-2.3.0rc6g

System:
CPU: AMD 9800X3D
Mainboard: MSI X870E Tomahawk Wifi
GPU: NVIDIA 5090
ZFS-Storage Hardware: 2x Lexar NVME NM790 4TB

ZFS-Layout:
Basic Pool over 2 NVME SSD with one dataset, all data resides in dataset (no data directly on pool).

(This is partly related to my post here: #458)

I am currently using ZFS in my "everyday gaming desktop" for real-life (stress) testing purposes.

Issues I experienced so far since testing for 2 days:

1. Certain games (e.g. Pax Dei) will only launch, if the relevant dataset has its own driveletter. Only assigning a driveletter to the pool does not work.

2. Age of Empires IV won't start all.

3. Computer crashed last time I closed Pax Dei. Since then starting the game fails with blue screen "unexpected kernel mode trap". Moving the game to a NTFS-filesystem and starting from there works.

More information (for what it's worth): minidump also points to ZFS being the Problem:

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
BugCheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a portion of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
Else
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
