SubjectRe: OOPS Report (swaper - ppp)

I noticed you are using the cyclom YeP, this may be relevant, I am
using linux 2.2.10/cyclades-z and the newest drivers from ftp.cyclades.com
and was experiencing oopses whithin programs using the cyclades ports and
only have an uptime of about (5 hrs to 1 day). Also I found out that there
was a LARGE RX errors on the cyclades ports but not on the onboard
ports(ttyS[01]). I discussed this with Ivan of cyaldes and advised me to
undef BLOCKMOVE from "/usr/src/linux/drivers/char/cyclades.c"

just change the first line from
#define BLOCKMOVE
to
#undef BLOCKMOVE

and recompile

after disabling the blockmove transfers, all my problem went away no more
RX errors and no more oopses :)

mail me if it works....
