The corruption is caused by not handling the head of the list specially. Here the sysinit in <sys/malloc.h> builds the list correctly, with M_ISADEV at the tail of the list. The first malloc(M_ISADEV, ...) then circularises the list. More serious corruption may occur later when malloc types are uninited on module unload. I fixed this by abusing ks_limit as an on-the-list flag. Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
