Hi all

Just tried linux-2.6.28-rc2 on same platform.

Same problem again...

Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.8.1 (Oct 7, 2008)
bnx2 0000:03:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
eth0: Broadcom NetXtreme II BCM5708 1000Base-SX (B2) PCI-X 64-bit 133MHz found at mem f6000000, IRQ 16, node addr 00:1e:0b:ec:d3:dc
bnx2 0000:07:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
eth1: Broadcom NetXtreme II BCM5708 1000Base-SX (B2) PCI-X 64-bit 133MHz found at mem fa000000, IRQ 16, node addr 00:1e:0b:ec:d3:d2
bnx2 0000:03:00.0: irq 45 for MSI/MSI-X
bnx2: fw sync timeout, reset code = 1030003
bnx2 0000:07:00.0: irq 45 for MSI/MSI-X
bnx2: fw sync timeout, reset code = 1030003
bnx2 0000:03:00.0: irq 45 for MSI/MSI-X
bnx2: fw sync timeout, reset code = 1030006


2.6.27.4 is running fine on this machine

Any ideas ?

Thank you

Eric
