I have no error messages in dmesg but everything grinds to a halt: Chromium browser takes tens of seconds to read fs cache, git fetch/pull takes tens of minutes, starting a new process or opening a file in vi may halt for a minute propably waiting for IO. iotop does not show much disk IO going on when things grinds to a halt. dmesg does not show any problems. top shows that swap is not being used since there's 8 gigs of ram. I tried to depict the issue with bonnie++. When the thing is dead slow after few days of uptime the results are: $ /usr/sbin/bonnie++ Writing a byte at a time...done Writing intelligently...done Rewriting...done Reading a byte at a time...done Reading intelligently...done start 'em...done...done...done...done...done...

Any ideas?
Can you please try "dd if=/dev/sda of=/dev/zero iflag=direct bs=1M count=100" when the system is in the slow state and post the output? Please also attach the output of dmesg. Thanks.

Grepping for a string in a 160 Mb vmlinux.o took over half an hour. I had played around with ext4 parameters relatime,data=writeback,barrier=0 on this file system but gone back to plain noatime, so maybe there's something I've screwed up. After "git clean -d -x -f"ing (which took ages to complete) the kernel tree I can now grep around with enough speed. iotop shows almost no disk access when things go to halt. I've used e2fsprogs 1.41.12-4stable1 from Debian squeeze/stable. Maybe a full fsck on the ext4 fs would help?

Just in case I had messed up the ext4 options, I re-installed the root fs but the problems are still there.
