Evening,
I'm not a big guru in kernel panic analysis but the parts:
Modules linked in: md5 ipv6 autofs4
i2c_dev i2c_core uhci_hcd 3c59x mii floppy ata_piix libata dm_snapshot
dm_zero dm_mirr
or ext3 jbd dm_mod 3w_xxxx sd_mod scsi_mod
Aug 15 23:01:28 mydomain kernel: Process ossec-syscheckd (pid: 11762,
threadinfo=c48f8000 task=c75a27e0)
may point to that ossec update.
regards
Jordi
