Strange error / warning message shortly after bootup

[Eric]

Shortly after booting up, I get (on the root console and in dmesg):

BUG: warning at kernel/softirq.c:138/local_bh_enable() (Tainted: P      )

  =======================

Any idea what that's all about?

I get it once and then everything seems fine.

Platform: Fedora 7 as "guest" OS on VMware 6.00 on Windows XP host, 256 MB 
RAM (1GB RAM on host, 256 MB allocated to guest OS, also tried it with 512 
MB allocated to guest with same result) (this has all been rock solid with FC6)
