CSCdp60104
A Cisco router that is running Cisco IOS Release 12.0(8) and is configured with a LAN Extender
(LEX) interface might display any of the following error messages:
%LINK-2-INTVULN: In critical region with interrupt level=0, intfc=Lex0
-Process= “RIP Send”, ipl= 0, pid= 73
-Traceback= 1A2006 66872 1A697A 22F1E4 22E924 22EAC0 380A36
%LINK-2-INTVULN:In critical region with interrupt level=0, intfc=Lex0
-Process= “IP Input”, ipl= 0, pid= 12

There is no workaround.

A Cisco router will exhibit traceback messages when the router sends Inverse Address Resolution
Protocol (ARP) messages for protocols like Novell, DECnet, and XNS. This situation will not
affect router operation. There is no workaround.
CSCdp65204
When using dialer profiles, the dialer state could get stuck in the call pending state. In this situation,
outgoing ISDN calls can no longer be initiated. There is no workaround.
CSCdp65743
Under certain conditions, the frame-relay inverse-arp command does not function properly for
IPX, Novell, DECnet, and VINES for multipoint interfaces. This situation is more likely to occur
when IP is running on the interface.
Workaround: Create a static map for IPX, DECnet, and other protocols by entering the
frame-relay map interface configuration command, or change the interface from multipoint to
point-to-point.
CSCdp86348
A Cisco 7500 series router that is running Cisco IOS Releases 11.1(31.1)CC, 12.0(9.1),
12.0(8.6)S1, 12.0(9)S, 12.1(0.8), and 12.1(0.8)T with a PA-A3 port adapter will not send
Operation, Administration, and Maintenance (OAM) cells. There is no workaround.
