My issue seems to be related not to ext4 or my memory but to my swap. I tried to download 2 times the same 30 Mb files without swap, and this time it was the same md5.
In addition, I tried to fill my swap partition with zeros, and I have an error: % sudo dd if=/dev/zero of=/dev/sda5 bs=1024 22293+0 records in 22293+0 records out 22828032 bytes (23 MB) copied, 16.7581 s, 1.4 MB/s 1331109+0 records in 1331109+0 records out 1363055616 bytes (1.4 GB) copied, 254.542 s, 5.4 MB/s dd: writing `/dev/sda5': Input/output error 2931829+0 records in 2931828+0 records out 3002191872 bytes (3.0 GB) copied, 471.766 s, 6.4 MB/s zsh: exit 1 sudo dd if=/dev/zero of=/dev/sda5 bs=1024 Is there any check done on swap partition ? Can the kernel detect errors on it ? Is there a way to avoid bad clusters with swap partitions ? I had also an issue (scrambled screen when booting) which disappeared but I can't be sure it was solved by the swap deactivation, as I tried several things at the same time (replacing kdm by gdm, removing splash at boot, and maybe an upgrade solved the problem). -- in-place corruption of large files *without fsck or reboot* reported with linux 2.6.31-14.46 on ext4 https://bugs.launchpad.net/bugs/453579 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
