Hello, I'm a newbie compiling kernels, but wanna learn. (I came here bacause i don't know how to solve this or where to find an answer). I compiled some few... but, in the last days i'm suffering an strange auto-remount of the root fs "/", (remounts like read only) it's temporally fixed using fsck and rebooting. But a time later of reboot, i'm working, and suddenly the same error comes again. it's really disturbing, because force to reboot often.
I think that is not a physical error. I did not have problems with badblocks. Something creates logical errors, either the auto-remount did
Surely I have something bad on the kernel, and probably have more things there than i must.
On the other hand my /var/log/lastlog is always full of an strange ASCII and i can't see the boot info.
this is my fstab:
/dev/sda6 / ext4 noatime 0 1
/dev/sda3 /home ext3 noatime 0 2
/dev/sda5 none swap sw 0 0
/dev/sr0 /media/cdrom auto noauto,ro,user 0 0
#/dev/fd0 /media/floppy auto noauto 0 0 No hay unidad de disco flsexible
proc /proc proc defaults 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
And a summary of my dmesg report

Your drive must be dying.
You can use SMART tools to check it.
The rigid and stiff will be broken.
The soft and yielding will overcome.
