Oh, and I forgot to add that I don't have xfsprogs installed since I don't have any XFS formated partition on my machine. That's a os-prober bug - it;'s trying to mount a device that does not contain an xfs filesystem as XFS. The error message you are seeing is not a kernel panic - it's XFS complaining about a filesystem corruption. That's not surprising because it's not an XFs filesystem that is on the device os-prober is trying to mount. os-prober is doing something actively dangerous - it can corrupt filesystems if it finds stale superblocks at the stale of block devices. I'm speaking from experience here - I purged grub2 from my all my systems the moment I discovered that my RAID devices were being corrupted by os-prober doing this.... BTW, I apparently can't change a damn thing realted to this bug, so I close it, reassign it, or anything else. So, please close this as not-a-bug. Well, I never saw the scary message before. It looked like oops to me. I thought it's a bug in kernel 3.10 since I didn't see it with earlier kernels. Thanks for the hint. I'll notify os-prober guys about this and start looking into syslinux. But anyways, I still think this shouldn't happen, so I'll still leave the bug open in case someone knows what's wrong.

That's because they are new in 3.9. Us XFs developers want to know when bad things are happening to XFS filesysetms. > > Thanks for the hint.

FYI, I am the guy that knows what is going on - I wrote the XFS code that generates the error message. So, yeah, what you report is expected behaviour, so you can close the bug. |
Created attachment 106980 [details] kernel config When I run os-prober to detect other oses on this machine, it tries to mount the partitions using several file systems (guessing). It tried to mount a extended partition and using XFS caused a Kernel OOPS.
