Binary package hint: linux-image-2.6.31-5-generic

When installing some of my new bl460c g6 blades with bnx2x 10GE interfaces, the step "detecting network hardware" takes a really long time. This is probably due to the installer scanning all interfaces several times, and these blades have 8 of them (each physical interface is split into 4 virtual one, each exposed as a nic by the kernel), together with a 50-second timeout in the driver.

50 seconds times 8 interfaces times 3-4 probing rounds makes for a total delay of 20-30 minutes, which is a bit painful.

The delay seems to be in "[bnx2x_wait_ramrod:6741(ethX)]timeout polling for state c0000 on IDX [1]". Attached is a sample screen of the installer messages.

I am booting a slightly modified (bnx2x dependencies added to the initrd) karmic netboot installer as of last week, will try the latest version as soon as #360966 gets fixed.
