One of its partition (/var) is mounted with this option yes. Actually,
this partition is moderately used (database, syslog server, etc.).

I also had three new messages yesterday (after reboot+fsck):
Mar 8 18:03:45 olan kernel: Unexpected dirty buffer encountered at do_get_write_access:618 (08:11 blocknr 920719)
Mar 8 19:03:54 olan kernel: Unexpected dirty buffer encountered at do_get_write_access:618 (08:11 blocknr 920707)
Mar 8 19:03:54 olan kernel: Unexpected dirty buffer encountered at do_get_write_access:618 (08:11 blocknr 920707)
I am still confused because the 08:11 pair does not match any
partition on my system:
# cat /proc/partitions
major minor #blocks name
8 0 8886762 sda
8 1 195568 sda1
8 2 976896 sda2
8 3 1952768 sda3
8 4 5761024 sda4
8 16 8886762 sdb
8 17 8886256 sdb1
# mount -t ext3
/dev/sda1 on / type ext3 (rw,errors=remount-ro)
/dev/sda3 on /usr type ext3 (rw)
/dev/sdb1 on /var type ext3 (rw,data=journal)
Thanks for your reply.
