Errors in dmesg Cubieboard 1: gpio-sunxi and UBIFS

[xanb]

Hi,

I receive this

$this->bbcode_second_pass_code('', '
# dmesg | grep error
[ 0.081173] gpio-sunxi: probe of gpio-sunxi failed with error -4
[ 2.022520] UBIFS error (pid 1): compr_init: cannot initialize compressor lzo, error -2
')

I'm booting from SATA.

What are these errors?
What can I do?

Thanks,
Xan.
