Ah, ok, mine is bigger (6577 bytes). After removing all comments it works bettter, but `gpio-ir` still not working (overlay is loaded but module `gpio-ir-recv` not, putting module into initramfs...

@pelwell Sure, it is already there ``` root@kmxbilr2 ~ # vcdbg log msg |& grep -vi hdmi 021804.939: brfs: File read: /mfs/sd/config.txt 021805.582: brfs: File read: 508 bytes 021969.696: brfs:...

@pelwell Here we go. Captured via tcpdump and investigated by Wireshark. Looks ok for me http://www.mediafire.com/file/jki8yl6tr06k13n/tcpdump.log/file

Initramfs is not the difference. Booted without initramfs into nfsroot, same issue ``` 027162.363: brfs: File read: /mfs/sd/config.txt 027164.041: brfs: File read: 3329 bytes 027295.131: brfs: File read: /mfs/sd/config.txt 027297.147:...
