Have you observed the same problems on the UP2 board?
Thanks,
Geoffroy

Hi Dubravko
All issues you mentioned are for Service OS, right?
Clear Linux image newer than 30900 fixed “memmap=2M$0x1FE00000” issue
BR.
Fuzhong
ACRN git commit hash is 555a03db99621c6a9d3bea0933c65db9dee44c46. I am getting identical behavior with ACRN that I've compiled, as well as with ACRN installed by Clear Linux (version
id 30770).
-
dmesg output from SOS
-
/proc/interrupts from SOS
-
loader.conf from EFI partition
-
acrn.conf (here I've verified that root UUID is correct, and I've had to delete settings related to hypervisor memory log because otherwise it crashed)
Our board has 8 GB of memory and 64 GB MMC, and is similar to Up Squared and Leaf Hill CRB.

Could you share:
1. ACRN last git commit hash
2. dmesg output in your SOS
3. the output of cat /proc/interrupt in your SOS
