Commit ef167e27039eeaea6d3cdd5c547b082e89840bdd ([TG3]: Fix supporting flowctrl code) breaks networking on IBM JS21 blade servers. If I revert this change from 2.6.26-rc2-git4, nfsroot for example will work again. There are no packages submitted, a tcpdump on a different host sees no broadcast messages.
Any ideas how to fix this? What info do you need from the system? I started with arch/powerpc/configs/ppc64_defconfig and updated CONFIG_CMDLINE for nfsroot. .... tg3.c:v3.92 (May 2, 2008) tg3 0000:10:04.0: enabling device (0000 -> 0002) eth0: Tigon3 [partno(none) rev 8003 PHY(5780)] (PCIX:133MHz:64-bit) 1000Base-SX Ethernet 00:11:25:c9:07:22 eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[1] WireSpeed[0] TSOcap[1] eth0: dma_rwctrl[76144000] dma_mask[40-bit] tg3 0000:10:04.1: enabling device (0000 -> 0002) eth1: Tigon3 [partno(none) rev 8003 PHY(5780)] (PCIX:133MHz:64-bit) 1000Base-SX Ethernet 00:11:25:c9:07:23 eth1: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] WireSpeed[0] TSOcap[1] eth1: dma_rwctrl[76144000] dma_mask[40-bit] ... full dmesg: Using pSeries machine description Page orders: linear mapping = 24, virtual = 12, io = 12 console [udbg0] enabled Partition configured for 2 cpus.
