Yesterday I had to reboot my machine.
Cleaning house, I had dislodged the plug for a power strip that powered
the computer, monitor, and printer.
Now, I am seeing very odd behavior.
Iceweasel hangs forever on some of the simplest tasks, such as loading a
static html page.
Not only that, but when it does so, other tasks on my machine are held
up. For instance, if I have iceweasel loading a page on my first
workspace, and try to load a message in mutt on another, mutt waits for
iceweasel to finish what it's doing before proceeding, which was not
previously the case.
I find this very, very odd.
Or even opening a terminal, for instance, a terminator, hangs, waiting
for iceweasel to finish its task.
It's as though iceweasel has dibs on system resources, and is blocking
other applications from using them, even when iceweasel, itself, is
using very few resources.
Now, when this is happening, I do not see any spikes in resource usage
that would explain slowing or stopping the entire machine while
iceweasel does its thing.
For instance, the machine will be using 2% of CPU and 4% of ram, but be
completely dormant until iceweasel succeeds in downloading a page.
This machine is a 2.8ghz x 4core AMD APU with 16gb of ram, too, so I'm
not exactly lacking in resources.
The only anomalies I have noted in dmesg, etc., are that some sectors of
my hdd are not reading correctly, or something.
A file system check forced on a second reboot yesterday failed, which is
disconcerting, but I'm not certain what to make of that.
dmesg | tail gives me

I don't know what to make of that.
Before the reboot yesterday, the machine was working awesomely.
This is Debian Stable, AMD64, as mentioned on a 2.8ghz x 4core AMD APU
with 16gb ram.
I use Openbox window manager with no DE (which further keeps things
generally humming long quite efficiently).
The machine is only 8 months old, essentially (mobo, cpu, ram all
purchased in January, although the hdd is over a year old, about 1 year
and a half, really, so still not very old).
What is going on here?
I ran aptitude update && safe-upgrade yesterday (had been about a week),
so everything is up to date.
