Follow-up fixes: . v2.6.38-rc1~442^2~19 (HID: Consolidate device existence checks in hiddev_ioctl, 2010-12-06) . v3.0-rc1~345^2^3 (HID: hiddev: fix race between hiddev_disconnect and hiddev_release, 2011-05-20) . v3.0-rc4~20^2~6 (HID: hiddev: fix potential use-after-free, 2011-05-24) . v3.0-rc4~20^2~4 (HID: hiddev: fix use after free in hiddev_release, 2011-05-26) Dmitry, I assume you can still reproduce this. Could you try a 3.x.y kernel from sid? The only packages needed from outside squeeze aside from linux-image-3.1.0-1-686-pae itself are linux-base and initramfs-tools.
