** Description changed:
Release: Kubuntu 8.10 x86_64
System: Lenovo ThinkPad T400
Kernel 2.6.27-9-generic
Symptoms:
- Various programs suddenly complain about filled root partition
- pty1 starts spewing out "Ext3 FS error: block xxxxxx already marked free"
errors as fast as it can
- When shutting down or restarting system simply halts and spews out the fs
errors for different blocks and never shuts down. Also dmesg and kernel logs
suddenly grow to many gigabytes in size (propably error messages, has happened
once) but i was unable to access them after fsck fix. If it happens again i'll
paste the output here.
+ 1) Various programs suddenly complain about filled root partition. (root and
/home partitions are ext3)
+ 2) df -h shows that of 27G 26G is used and 0% is free.
+ 3) pty1 starts spewing out "Ext3 FS error: block xxxxxx already marked free"
errors as fast as it can (and never stops), it's impossible to escape the
console back to the desktop.
+ 4) When shutting down or restarting system simply halts and spews out the fs
errors for different blocks and never shuts down.
+ 5) Also dmesg and kernel logs had suddenly grown to many gigabytes in size
(propably error messages, has happened once) but i was unable to access them
after fsck fix. If it happens again i'll paste the output here.
+ 6) This has happened three times with the new kernel. Last time it happened i
was recording a screencast of my desktop and wondered why the recorded output
video contained only parts of the whole recording. Also, hdd usage was random
when recording videos (half of the time no write activity and then a big burst)
- After rebooting the system following errors on root partition are found after
manual fsck:

Inode bitmap differencies (a few dozen)
free blocks count wrong group #0 (hundreds)
inodes part of a corrupted orphan linked list found (in the thousands)
inode has zero dtime (a few)
- Fixing is succesful and system can be rebooted and used normally
+ Fixing manually was succesful and system can be rebooted and used
+ normally. I noticed some of my personal settings (such as firefox addons
+ and some desktop setings) had gone awry which i'm storing on a separate
+ /home partition. I haven't found any corruption in my image or music
+ files but I find that some files are just missing completely.
- I don't remember experiencing this problem with 2.6.27-7, but after
- upgrading and booting into 2.6.27-9 it has started to happen. I've
- checked the health of my system and everything seems fine on the hw
- side.
