a quick question regarding debugging the currently-running kernel with gdb. after compiling the kernel with debugging info and rebooting, i started the debugger with: # gdb vmlinux /proc/kcore and, as a test, tried: (gdb) print jiffies what i got printed was a *negative* number, which struck me as odd -- it was around -150000. it took only a few minutes for that to finally click over zero and become positive but is there some reason that the number of jiffies since boot time would display as negative, at least temporarily? rday p.s. i checked the System.map file for the kernel and located the hex address for "jiffies" and printed that as well, and it matched what i got from the previous command, so that makes me think i am at least printing the correct address contents. -- ======================================================================== Robert P.
