I don't see a way to turn it off for the SB-16. If I enter 0 for base address will that do it? If I enter a blank, it pops to 330 which my aha-2940 uses.
I tried to go UGH hunting by adding the following to copy_to/from_user and get/put_user. I didn't find any, and the machine still locked tight.
I'm wondering if the test might be wrong. WRT the sti().. I booted my mirror and prayed fervently that I wouldn't see a zillion UGHs go by :)
{ unsigned long _flags; save_flags(_flags); if(!(_flags & (1<<9))) { printk("UGH!: <%s,%d>.\n",__FILE__,__LINE__); sti(); } .... restore_flags(_flags); return_if_func_has_one; }
