Curious problems with /proc/kmsg?

[lmage11]

I'm currently trying to debug a problem with my wireless driver,
and while looking at the copious output that the driver produces,
I've been noticing some very odd stuff come out of /proc/kmsg (which
is also where my syslog daemon gets kernel messages). 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

Any comments? I'm using 2.6.28.

Thanks!
