Kernel call traces
When running Linux on top of Dom0, Linux can go in kernel panic due to insufficient memory for dom0. Example:
[ 12.747244] dump_backtrace+0x0/0x190 [ 12.747750] show_stack+0x18/0x30 [ 12.748176] dump_stack+0xd4/0x110 [ 12.748530] dump_header+0x48/0x1e8 [ 12.748902] out_of_memory+0x2c4/0x310 [ 12.749289] __alloc_pages_nodemask+0x72c/0xc64
Solution
Increase the dom0 allocated memory. Check xen_boot_tftp.source or xen_boot_sd.source relevant file and see “dom0_mem=1G”, increase this memory appropriately to > 1G. Save the file and recreate the xen_boot_tftp.scr using below command:
mkimage -A arm64 -T script -C none -a 0xC00000 -e 0xC00000 -d xen_boot_tftp.source xen_boot_tftp.scr
Reboot the machine with latest scripts.
