Description Konstantin Olchanski 2006-01-19 20:03:53 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.10) Gecko/20050909 Fedora/1.7.10-1.3.2

Description of problem:
In disklessrc::loadmodules() the line "grep "^$MODULE" /proc/modules" prevents the e100 network driver from being loaded if the e1000 driver is already loaded ("grep ^e100 /proc/modules" erroneously matches the e1000 entry).

This results in an unbootable machine because without the e100 driver it does not see the network and booting stops. Connecting the network cable to the GigE interface (the e1000 driver) does not work because the PXE BIOS cannot boot from that interface.

A possible fix is to modify the "grep" line like this:
        if ! `grep "^$MODULE " /proc/modules > /dev/null`; then

Notice the extra space after $MODULE.

Thanks for pointing out the "^$MODULE" ->  "^$MODULE " change - will apply
today with s-c-nb-0.1.38-1 .

BTW, I've no problems with PXE booting with my e1000 on an IBM Thinkpad T41 .

Fixed with system-config-netboot-0.1.37, now in rawhide
