Once I reboot (either from yesterday's (r305058) kernel or from the stable/11 or stable/10 slice), I should be able to make the dump available via my Web server. I'm about to build head@r305116 on my laptop (as well); I plan to follow up to indicate whether it exhibits similar behavior (or not). Peace, david --=20 David H.
