Hello to all, I'm Toni and it's my first Kernel bug. I hope help to detect
problems on kernels (I'm not developer but yes detector ;))

Ok, and now start.

When I dump image into SD card with IO operations apparently ok, and it
continue past 100% (cache flushing) I can see that the writing is not 100% busy
time on the output device. The IO monitor show this.

For example, I can show: 100% 1 second, 0% 1 second, 100% 2 seconds, 0% 0,5
seconds...

AND, in some situations, the umount on FAT32 on USB drives sometimes not really
umount well, but this is other war.

Cheers!
