one bug is in ac97write. there's a memmove into user memory with an ilock held. that's a no-no, since you could take a page fault.you can get a better handle on which qlock is causing the problem by converting the address given on the console to the qlock in question. - erik
hi, thanks, i'll look at it in the next few days. i'm too busy now. i'll try to let it coexist with the soundblaster code. markus
