[syslinux] System freezes after "Loading iramfs.gz... ok"

[Erik Rull]

This was an Elkhart Lake based Q7 board by congatec.
I've seen an identical behavior for the Dell R250 server racks. The previous
version (R240) worked just fine.
32 bit => freeze as described and 64 bit just booted off with close to identical
kernel config (just switched to 64 bit).

Any hints what else could have caused that would be really helpful.

Best regards,

Erik
