Malformed packets in DHCP challenge

Matteo Brusa
Hi,
I have an AR 5212 as access point, encryption is off; the client is a
Nokia E51.
Some packets get mangled, and the DHCP challenge never concludes.
Here is a tcpdump of the dialog:
http://62.143.54.15/madwifi.pcap
And here a tcpdump of a similar dialog, using an Asus AP:
http://62.143.54.15/ap.pcap

dmesg after modprobe:
[294740.770000] AR5210, AR5211, AR5212, AR5416, RF5111, RF5112, RF2413,
RF5413, RF2133)
[294740.820000] ACPI: PCI Interrupt 0000:00:14.0[A] -> Link [LNKB] ->
