YÚN read big file issue

Hello

I am trying very simple code on YÚN for reading file from SD card file and writing to Serial console. I see on console different data than these in file. There is something added. Any idea? Can anybody replicate. My file is about 30kb.

#include <FileIO.h>
void setup() {

Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
Bridge.begin();
FileSystem.begin();
}
void loop() {

File dataFile = FileSystem.open("/mnt/sdcard/data.txt", FILE_READ);

if (dataFile) {
while (dataFile.available()) {
byte d = dataFile.read();
Serial.write(d);
delay(50);
}
dataFile.close();
}
else {
Serial.println("error opening data.txt");
}

Serial.println("end");
delay(10000);
}

Thank you, Skoky.

Can anybody confirm this on another YÚN? Thank you in advance!

I have upgraded YUNs firmware to latest version and there seems to be the same issue

Can anybody confirm/replicate or fix?

Thank you, Skoky.
