Strange brakes in Ubuntu 10.10?

Question

linux

Periodically there are freezes in the system. As if the connection between hard and PC is temporarily lost. Until now, I have sinned on a dying screw, but dmesg says nothing. This also happens when copying data to a USB flash drive. The load on the CPU is not more than 40% constantly.
Here is an extract from dmesg:

[321931.255048] lo: Disabled Privacy Extensions<br/>
[323536.583112] lo: Disabled Privacy Extensions<br/>
[324134.241403] lo: Disabled Privacy Extensions<br/>
[369304.658921] lo: Disabled Privacy Extensions<br/>
[370517.383322] lo: Disabled Privacy Extensions<br/>
[384408.354759] lo: Disabled Privacy Extensions<br/>
[400648.386750] lo: Disabled Privacy Extensions<br/>
[401422.574090] nautilus[21161]: segfault at 83e58962 ip b708fd2d sp bfa1aff0 error 4 in libgobject-2.0.so.0.2600.0[b7069000+40000]<br/>
[404399.246580] lo: Disabled Privacy Extensions<br/>
[409948.549135] lo: Disabled Privacy Extensions

I somehow paid attention to lo: Disabled Privacy Extensions , it is unlikely that all these problems are due to it.

Answer 1

2 months were similar suspensions and brakes when copying. Even when installing the software via apt-get, at the moment reading database xx% pedaled hard and took about 40-50 seconds. Process is not loaded. Memory is free, etc. I thought screw. I checked for bad sectors a couple of times. All is clear. Then the system fell and did not rise in any way.
Bought a new screw. I found out that reading database takes 2 seconds max and forgot about the brakes and freezes.
