Bug#697801: linux-image-3.7-trunk-amd64: [experimental] Spurious (harmless) soft lockups with kernel 3.7



Package: src:linux
Version: 3.7.1-1~experimental.2
Severity: normal

Dear Maintainer,

I encounter soft lockups with kernel 3.7 when running mksquashfs. As the fs
generation completes it seems the reported lockups are spurious and harmless.
This can be reproduced with e.g. :

  mksquashfs /lib tmp.squashfs

(at least, it triggers each time on my ht-enabled core i3 showing 4x cores.)

Sample terminal messages:

---

(Details in kernel log below.)

This is not happening with kernel 3.6 (or earlier).

Best regards,

V.
