Description

Hello,

We observe a subsequent Kernel panic errors caused by Ldiskfs, the cause is unknown, the hardware underneath looks healthy. Netconsole dumps in attachement. Panics happen quite often, more or less once per day per server. We are trying to trace which job might be causing it, but it's not an easy task - if we catch the user/job, I'll update the ticket. Does anyone have any idea what can be wrong?

Regards,
Marek Magrys
