SubjectRe: Kernel 2.2.12 oops (swaper - cyclades - ppp)

I have experienced oops like this using the newest driver provided by
cyclades (also in 2.2.12). Check if you are also encountering high TX
errors(use ifconfig), if the answer is yes then most probably
there is a bug in the optimization BLOCKMOVE routine. Talked to ivan about
this and he suggested to undef it in cyclades.c. Undefining BLOCKMOVE and
recompiling made my kernel stable as a rock (no more oops and TX errors.)

hope this helps,

Rodel
