Hello Gentooers! I am expieriencing some issues with Suspend/Resume (no matter if RAM or disk). After resuming, There seems to be a kernel bug:

An additional but probably unrelated issues is related to my wireless card. It gets disconnected after resume: wlan0: authenticate with AP 00:1c:4a:1f:a1:b1 wlan0: RX authentication from 00:1c:4a:1f:a1:b1 (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:1c:4a:1f:a1:b1 wlan0: RX ReassocResp from 00:1c:4a:1f:a1:b1 (capab=0x411 status=0 aid=1) wlan0: associated wlan0: CTS protection enabled (BSSID=00:1c:4a:1f:a1:b1) wlan0: deauthenticate(reason=3) I am using gentoo-sources-2.6.26-r1.
