Hi, I'm trying to PXE boot a cluster of machines using 3Com 3C996B-T gigabit Ethernet NICs and appear to be running into driver problems specific to PXE booting. Here's what I know:
- The system boots just fine off of an Intel card with PXE support.
- The 3Com NIC basicly works (some phy issues remain) if you boot via
normal methods (I did an FTP install of todays -stable snapshot off of
a floppy to verify this.)
- When booting with the 3Com NIC, the kernel loads correctly, but the
does not proceed beyond:
Mounting root from nfs:
NFS ROOT: XXX.XXX.XXX.XXX:/nfsroot
Running tcpdump on the nfs host seems to indicate that the system
is attempting to do an NFS lookup on sbin on it's way to running
/sbin/init. The responses appear to be sent correctly, but printfs
added around the call to ether_input indicate that they never make
it out of the card. ARP responses do appear to arrive properly as
do pings.
Does anyone have any suggestions with regard to debugging this problem?
Thanks,
Brooks
