After the latest update that I performed this morning my RPI3b hangs for several minutes (~3) before booting. I actually thought it had crashed and I found out by accident that it eventually continued booting. It hangs at this line:
$this->bbcode_second_pass_code('', '
...
Found U-Boot script /boot.scr
723 bytes read in 95 ms (6.8 KiB/s)
## Executing script at 02c00000
')
then says something about having read 34 MB in 180000 ms (approximate values) and relocating something but then the screen is cleared and the boot process starts so I don't have time to read the details.
