From 0d644e918532f7eba2b02e0eaf60ee1a1b20a856 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 6 Aug 2022 21:52:23 +0200 Subject: um: increase default virtual physical memory to 64 MiB The current 32 MiB of RAM causes OOMs to appear shortly after booting in a minimal OpenWrt 22.03 configuration with a 5.10.134 kernel. Of course, passing a "mem=64M" (from the --help text) parameter works too, but it produces the following (info) message: | [ 0.000000] Unknown kernel command line parameters "mem=64M", will be passed to user space. That's why, I think it would be nicer, if this is working out of the box again :).
