There is code in the parameter ioctl() call to do this, but it doesn't actually set CSR11 with the value intended.

Yes, that's the suggested hack. Right now that only happens when the 21143 (only!) chip is first overloaded. -- Donald Becker [email protected] Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 _______________________________________________ tulip mailing list, [email protected] To change to digest mode or unsubscribe visit http://www.scyld.com/mailman/listinfo/tulip
