Details

Description:

After upgrading to kernel 3.5, the kernel panics whenever I attempt to mount a partition using ATA over Ethernet (AOE).
The aoe module loads OK and the aoe-discover and aoe-stat utilities correctly identify the drive, but the kernel panics when the mount command is executed.

Additional info:
* package version(s)
Kernel: 3.5
Aoetools: 30
Vblade (running on server, not on client machine that is panicking): 20


* config and/or log files etc.


Steps to reproduce:
1. Boot using Linux kernel 3.5 from Arch testing.
2. modprobe aoe
3. mount a partition over aoe and the kernel panics.
This task depends upon

Update: The kernel panic only happens when there are multiple AOE targets. For example, I was using 2 Gig-E adapters to communicate with the server, but when I killed one of the vblade instances on the server, the mount proceeded without crashing.

The bug still exists, but is now limited to using multiple AOE targets in parallel. I have been using this configuration for over 2 years and many kernel releases, so this is a regression.

Without giving more information about the traces in the kernel panic, nobody will fix this for you.

We can't fix here anything please report upstream.

I'll report upstream. Sorry for the lack of traces but kernel panics are not the easiest things to log.

They are easy with nullmodem

You can go ahead and close this bug. The latest kernel packages (linux 3.5.3-1) have fixed the problem.
