Subject: Re: [2.5.68] Scalability issues
Date: Sun, 4 May 2003 21:44:51 +0200 [thread overview]
Message-ID: <20030504194451.GA29196@codeblau.de> (raw)
In-Reply-To: <20030504173956.GA28370@codeblau.de>
Here is the ksymoops output. The taint came from the nvidia kernel
module, X was not running, so the module did not do anything at the
time.
ksymoops 2.4.1 on i686 2.5.68. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.68/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
e100: selftest OK.
e100: eth0: Intel(R) PRO/100 Network Connection
