Package: linux-2.6
Version: 3.0.0-1
Severity: important
Hello,
I have a xen host running debian squeeze, amd64, some of the DomU's are
running wheezy. My mail server is a DomU called "mail", using ext4 for the
root (and other) FS. A dist-upgrade on "mail" has upgraded the kernel to
linux-image-3.0.0-1-686-pae, and at this point I started getting I/O errors
during the boot process, as follows:
-----------
Starting MySQL database server: mysqld[ 6.453894] end_request: I/O error, dev xvda, sector 4456704
[ 6.453919] end_request: I/O error, dev xvda, sector 4456704
[ 6.453964] Aborting journal on device xvda-8.
[ 6.462873] EXT4-fs error (device xvda): ext4_journal_start_sb:296: Detected aborted journal
[ 6.462903] EXT4-fs (xvda): Remounting filesystem read-only
[ 6.463276] journal commit I/O error
. . . . . . . . . . . . . . failed!
Starting MTA: exim4.
Starting IMAP/POP3 mail server: dovecot.
startpar: service(s) returned failure: mysql ... failed!
-----------
So I went ahead and installed wheezy on a brand new DomU, and this
was repeated immediately when booting the machine after the installation
completed.
-----------

ln: creating hard link `/var/log//dmesg.0': Read-only file system
... etc. ...
-----------
Now, it happenes this way exactly every _other_ time the machines boot.
When I reboot after these I/O errors, fsck is run and then the machine
seems to be actually fine until the next reboot when it all happens
again.
For me, this is happening on xen DomU's, only when running linux
3.0.0-1-686-pae, only when using ext4 for the root FS.
No problems when booting back to 2.6.39-2-686-pae.
Please let me know what more specific testing needs to be done, if
necessary I can test more platforms / flavors.
I have observed nothing to suggest this is related to xen, it's just my
platform here.
