I saw a slab corruption message in my log files after disconnecting a USB Serial device (a Crystalfontz CFA-635 LCD panel). I have included surrounding log lines from the smbd service because I suspect that the corruption may have caused it some trouble. The kernel is Mandriva's x86_64 2.6.16-rc5.13mdksmp.
