1. I had some problems in F 11 with my motherboard and display driver:
This I started reporting on 19th April 2009, without any solution till
now. I expected the problem to go away with F 12, but it did not. In
fact, as I reported in the bug today, that, in F 12 it became bigger.
So I went back to F 11 (with nomodeset in the kernel line).
2. Today, I was doing scp between my laptop (F 12) and desktop (F 11),
some ogg files I was copying from the desktop to the laptop. And a
most queer thing happened. I was so surprised that I took a
screenshot, and I am attaching that PNG with it. All the files on the
laptop was showing exactly the double size of that on the desktop. As
you can compare in the screenshot. The terminal on the left is
dd@mamdo, which is my desktop, and this is on SSH. And the terminal on
the right is dd@dia, that is, my laptop where I took the screenshot.
'ls -sh' showing exactly double size, 'ls -s' showing exactly the
double number of blocks, though the 'md5sum' for both of them is
generating the same number. Both of them are on EXT4. This is
something that is explosively beyond my comprehension. As you can see
in the screenshot, some package update was going on, I rebooted after
it. Expected it to go away: some kind of misreporting. But, it is
showing exactly the same thing till now.
