Hi Fumihito YOSHIDA,

I think that my case is 1, because:

the problem could be related with wifi firmware bug, I don't have corruption
with wired connection,

if I use apt-get update and apt-get dist-upgrade and I'm on wifi connection
I have error on ext3 partition

I have check: HDD ( with seatool test al test passed ), Memory ( also check
memory and no problem was found )
I have that on dmesg

[   44.001108] Clocksource tsc unstable (delta = -76736091 ns)

it could be an CPU troubles?

the laptop has a week of life, is an Compal-KHLB2
