autoinstall 20.04 with 2G (fails) and 4G (works) install netboot

[Jerry Geis]

So trying to find why my 2G ram (does not autoisntall) and the 4G does.

ubuntu-server kernel: [   40.237245] kworker/7:1 invoked oom-killer:
gfp_mask=0xdc0(GFP_KERNEL|__GFP_ZERO), or|  ubuntu-server
subiquity_log.2170[2380]:   "LABEL": "",

  ubuntu-server kernel: [   40.237250] CPU: 7 PID: 225 Comm: kworker/7:1
Not tainted 5.4.0-65-generic #73-Ubuntu|  ubuntu-server
subiquity_log.2170[2380]:   "LOG-SEC": "512",

  ubuntu-server kernel: [   40.237251] Hardware name: QEMU Standard PC (Q35
+ ICH9, 2009), BIOS 1.13.0-1ubuntu1.|  ubuntu-server
subiquity_log.2170[2380]:   "MAJ:MIN": "252:0",

  ubuntu-server kernel: [   40.237282] Workqueue: events
drm_fb_helper_dirty_work [drm_kms_helper]


I found this in the syslog on the 2G ram install side.
I am trying to do the netboot and specify the ramdisk_size=1500000 and
root=/dev/ram0 on my kernel line along with ip=dhcp and
url=path_to-_live_server.

This all works in 4G ram - but 2G ram does not.  I think it's supposed to.
What else can I look at to get autoinstall for 2G ram to work ???
