I'm getting stuff like: Jan 1 01:59:02 tank ieee80211 phy0: I iwl4965_mac_tx enter Jan 1 01:59:02 tank ieee80211 phy0: I iwl4965_mac_tx leave Jan 1 01:59:02 tank ieee80211 phy0: I iwl4965_mac_tx enter Jan 1 01:59:02 tank ieee80211 phy0: I iwl4965_mac_tx leave Jan 1 01:59:03 tank ieee80211 phy0: I iwl4965_mac_tx ente Jan 1 01:59:03 tank 3ie821py:Iil95mct ev Jan 1 01:59:03 tank 3ie821py:Iil95mct ne Jan 1 01:59:03 tank 3ie821py:Iil95mct ev Jan 1 01:59:03 tank 3ie821py:Iil95mct ne Jan 1 01:59:03 tank 3ie821py:Iil95mct ev Jan 1 01:59:03 tank 3ie821py:Iil95mct ne Jan 1 01:59:03 tank 3ie821py:Iil95mct ev As you can see, the first few lines are fine, but the next few lines are complete nonsense. It looks to me as if characters are getting semi-randomly "skipped" sometimes, or something??? Very strange. This oddity does not show up when I look at the kernel output through dmesg. Some more examples of strange output follow: Jan 1 01:59:04 tank w46_a_xlae<>ee01 h0 w46_a_xetr<>ee01 h0 w46_a_xlae<3>ieee80211 phy0: I iwl4965_mac_tx enter Jan 1 01:59:04 tank ieee80211 phy0: iwleqeehm edn omn ESTVT_M #8,sq x46 8btsa 6[]4<>ee01 h0 w_eei_m_alakbc rmSNIIIYCD(x0000 Jan 1 01:59:05 tank 3ie821py:Iilgnrccdclbc akfo EL_XLN_ULT_M 00000)<>ee01 h0 w46_a_xetr<>ee01 h0 w46_a_xlaev Any comments?
