Info about DWARF2 unwinder pls

[Deepak Shrestha]

Hi,

Yesterday my FC5 box hanged about 5 mins after complete boot. In next
reboot, what I found in /var/log/messages is:

===============
Dec  5 23:04:05 zeesrvr kernel:  [<c04038a1>] error_code+0x39/0x40
Dec  5 23:04:05 zeesrvr kernel: DWARF2 unwinder stuck at error_code+0x39/0x40
Dec  5 23:04:05 zeesrvr kernel:  [<c04038a1>] error_code+0x39/0x40
===============

I am more on a fedora user but want to learn more. This message
doesn't make sense to me.
tried looking at man pages about dwarf2 but no info. Googling gives me
more on discussion about it than the info.

I will be grateful if somebody explains me what this message really
about (what could probably be wrong with my computer) and what this
"DWARF2 unwinder" do.

Thanks
