TITLE: Manhattan P/V SMC PCI Ethernet Card


SUMMARY

   The SMC PCI Ethernet card may hang under heavy I/O in a 
   Manhattan P and V system when sharing interrupts.

   This issue applies to the following systems: 501500, 501502, 501503,
   and 501830. 


ISSUE

   While running Netware 4.1 on the Manhattan P or V system, the SMC 
   PCI NIC may hang under heavy I/O when the card is installed in the
   second PCI slot, which shares an interrupt with the on-board NCR 
   controller.  A cold boot may be the only method to gain access to 
   the server.


BACKGROUND

   The use of earlier versions of NCR and SMC drivers cause the system
   to hang.


ACTION

   Ensure that all the drivers are current.
