Table 1-3 Table 1-4 FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 PHNE_17061 (Continued) Symptom Defect 6. System crashes, with either an HPMC or a memory protection fault panic, under high network traffic over the EISA FDDI interface. 7. System panics with an instruction page fault when multiple promiscuous streams are enabled over the EISA FDDI interface. 8. The netfnt(1M) output for traces generated by the EISA FDDI driver is incorrect. 6. Under heavy network traffic conditions, the EISA FDDI driver may sometimes invoke internal card resets to recover from transmit hangs. In the driver's watchdog timer, when attempting an internal reset (for automatic recovery), the driver invokes a kernel sleep routine while waiting for reset completion. Since the watchdog timer executes in an interrupt system context, calling sleep leads to a system crash (HPMC or memory protection fault). An alternate mechanism of completing resets in driver interrupt routines has been implemented. 7. When multiple streams enable promiscuous mode on a single interface, the driver failed t distinguish between bound and unbound streams. As a result, the streams queue pointer was corrupted, resulting in a panic. 8. The EISA FDDI formatting routines were using incorrect offsets into the trace buffers, resulting in incorrect output. PHNE_15665 Symptom Defect 1. The EISA FDDI interface may hang after logging the message, "Waited for stat2_ine4 but it never came" to syslog. 1.A software reset mechanism was introduced in the EISA FDDI driver to work around hardware defects in the Motorola FDDI system Interface (FSI) chip. This mechanism did not detect all the circumstances under which the card had to be reset. Chapter 1 19
