I should have stated in the previous bug-report posting that when this samba failure occurs, it also locks up the system hard. A reset button or on-off switch are required to "recover". Please consider upgrading this bug to "severe" or "grave" since this conflict could potentially cause a complete failure of a system.
I use reiserfs, so I was in pretty good shape. This failure caused 5 hard crashes before I figured out the cause.
I am now holding my system at libc6 2.3.1-17 until this bug is fixed and I have had no more problems !
