"status = -30" means it has encountered EROFS when start transaction.<br>
And system panic is because you mount with option "errors=panic",<br>
while default is "errors=remount-ro" rather than panic.<br>
Change it to "errors=continue" will proceed even if filesystem<br>
encounters errors (default will set it to readonly).<br>
<br>
Thanks,<br>
Joseph<br>
