Hi all,
I'm running FreeBSD 6.1-PRERELEASE on a Samsung X20 laptop.
Sometimes, after resuming from a suspend state, the following messages
show up in the messages file:
Mar 4 11:21:13 hermes kernel: iwi0: could not allocate firmware
DMAmemory
Mar 4 11:21:13 hermes kernel: iwi0: could not load main firmware
Mar 4 11:21:13 hermes kernel: iwi0: _ieee80211_crypto_delkey:
NONE keyix 65535 flags 0x3 rsc 0 t sc 0 len 0
The last message is because debug was on.
After that the system was dead and eventually it rebooted. A dump was
written:

Is this enough information for filing a PR? Am actually not quite sure
if the error is within wpa_supplicant or within iwicontrol?!
