I get a complete system crash when trying to dump packets with airodump-
ng, while sending arp-request with aireplay-ng. When aireplay starts
sending, the system freezes completly. Sometimes the kernel gets a warning
out, saying i probably have a problem with my RAM modules.
i checked my RAM with memtest, it didnt find any errors in 8 hours. I only
have 1 module, so i cant rule out the hardware for sure, but the machine
runs just fine, except this problem.
Airodump or aireplay running alone does not cause any problems.
This is what i found in my sylog:
{{{

Jun 1 13:42:55 localhost kernel: device ath0 entered promiscuous mode
Jun 1 13:44:17 localhost kernel: Uhhuh. NMI received. Dazed and confused,
but trying to continue
Jun 1 13:44:17 localhost kernel: You probably have a hardware problem

Jun 1 13:44:20 localhost kernel: ath0: ath_reset: unable to reset

Jun 1 13:44:26 localhost last message repeated 2 times
Jun 1 13:44:27 localhost kernel: device ath0 left promiscuous mode
}}}
this is what dmesg has to say:
