Hello list, Today, when I tried to switch down my computer I got this message: (copied in the next boot from /var/log/messages, so I lost the traceback, sorry) Jan 15 13:24:38 hammer kernel: DWARF2 unwinder stuck at system_call+0x7e/0x83 The system finally went down shutting down services as usual. The point is that greping my messages file, I found more than 15 occurrences of this. What does it mean? Thanks in advance -- Kernelnewbies: Help each other learn about the Linux kernel.
