I've got some more.
After mounting the disk with "softdep" option, I saw this message on the
console a short while before the crash :
ehci_sync_hc: tsleep() = 35
ehci_sync_hc: tsleep() = 35
ehci_sync_hc: tsleep() = 35
ehci_sync_hc: tsleep() = 35
/var: got error 5 while accessing filesystem

Then, the ddb prompt showed up, but I wasn't sure what to do next.
Please, tell me how to give you more relevant information to solve this
issue.
Regards.
