Howdy all,
I'm netbooting into the Fedora (test 1.90) installer, and the installer is having a hard time aquiring a lease from my DHCP server (ISC DHCP version whatever's-current-in-redhat-9). I see the requests going out, an the following errors in the syslog on the DHCP server:
Feb 27 19:54:38 flowers dhcpd: fallback_discard: Resource temporarily unavailable
What's more:
- The PXE loader (pxelinux) is able to aquire a lease w/o a problem, and - The second stage installer is also able to aquire a lease.
This system is using a 3Com 3C905C-TXM NIC.
I recall seeing a similar issue discussed in the archives, but I'm unable to search the archives at the moment ("redhat.com is temporarily unavailable. Please try back later."). Has anyone else run into this problem?

I have a working 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74)
I did have a rev B card that was troublesome and no longer have the card.
By my thoughts, it is something other than the NIC. I believe it only effected revs before C.

"You see what I mean? There's *always* that doubt!"
I'm netbooting into the Fedora (test 1.90) installer, and the installer is having a hard time aquiring a lease from my DHCP server (ISC DHCP version whatever's-current-in-redhat-9).
It definately looks like a software problem. The DHCP requests sent out by the stage-1 DHCP client have an incorrect UDP checksum. Here's the result of a packet capture (output from 'tethereal -v'):
User Datagram Protocol, Src Port: bootpc (68), Dst Port: bootps (67) Source port: bootpc (68) Destination port: bootps (67) Length: 308 Checksum: 0x0145 (incorrect, should be 0xb041)
This problem *only* occurs during the stage 1 installer; both the PXE bios and the second stage installer (and the subsequent Fedora install) are able to aquire a DHCP lease without a problem.

With test1, add selinux=0 to your boot command line (this was put in the isolinux.cfg at the last minute to work around a kernel bug which has since been fixed)

That makes my life *so* much easier. Thanks!
