Two 386 bugs of major note: 1. POPAD with a prefix (16/32bit in the opposite mode crashes some CPUs) 2. 32bit MUL is faulty in some _very_early_ 386 chips
Also 486 bugs including: 1. Ability to write outside of your segments by about 4 bytes with a really dubious complex to set up trick.
See www.x86.org some day - some quite fun pentium/486/386 features
