Once the daemon is running the messages disappear. Searching the source of isic_isac_irq() for this message I only found similar stuff like i4b-L1-isic_isac_irq: RME, error or input buffer overflow If not preceded by another ``i4b-L1-isic_isac_irq'' this means that the irq routine thinks to receive a frame longer than 260 bytes, which shouldn't happen (both the thinking and frames longer than 260 bytes on the D-Channel) If preceded by another ``i4b-L1-isic_isac_irq'' message, this only indicates a secondary error message and the first one is the really interesting one. > Anyway, the whole thing is harmless and does not in any way impair the > functionality of i4b. OK, but... you never know ... Maybe this bug is worse on another system. Wolfgang To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
