Ethernet cable is around 5m in length (short cable fix invoked). The patch below fixes the problem for me. >How-To-Repeat: Run sis0 in 100baseTX mode. Disconnect ethernet cable for less than 4 seconds. On reconnection, short cable fix reg is 0, and sis0 interface is non-functional. >Fix: Apply the following patch to sys/pci/if_sis.c --- if_sis.c.orig Fri Apr 27 12:41:14 2007 +++ if_sis.c Fri Apr 27 12:41:32 2007 @@ -1909,7 +1909,7 @@ if (sc->sis_type == SIS_TYPE_83815 && sc->sis_srr <= NS_SRR_15D) { CSR_WRITE_4(sc, NS_PHY_PAGE, 0x0001); CSR_WRITE_4(sc, NS_PHY_CR, 0x189C); - if (sc->sis_srr == NS_SRR_15C) { + if (sc->sis_srr <= NS_SRR_15D) { /* set val for c2 */ CSR_WRITE_4(sc, NS_PHY_TDATA, 0x0000); /* load/kill c2 */ >Release-Note: >Audit-Trail: >Unformatted:
