I've got some stuff that *was* all ready to commit-- it fixes one major and a few minor problems with the DMA code. (The major problem involved probing for and storing the alternate status port address for PCI controllers). I've been lame about sending it along and getting it committed. The whole wd disk driver really needs a rewrite; there's all kinds of problems in there. I've made unenthusiastic noises about doing this in the past, and I certainly haven't written any code... Soren/John, email me in private so we can smash our code together again, eh? --jh -- Mr. Belliveau said, "the difference was the wise, John Hood, cgull intelligent look on the face of the cow." He was @ *so* right. --Ofer Inbar smoke.marlboro.vt.us To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
