I noticed in an article at: http://marc.theaimsgroup.com/?l=linux-kernel&m=101096234600708&w=2 and another at: http://www.uwsg.iu.edu/hypermail/linux/kernel/0201.1/0809.html that people were getting oopses in kswapd. I also had the same problem this morning. The kernel froze up totally. Not even SysRq keys would work. I am running 2x400mhz PII in an SMP machine with 512mb RAM. I have attatched the syslog of the oops and what I got when I ran it past ksymoops. I'm using 2.4.17 on a stock Red Hat 7.2 machine. I built it with gcc 2.96 (the 2.96-98 version that comes with red Hat 7.2.) Can anyone help me out? I'm not subscribed to this list, so please cc me any advice. Thank you very much. -Patrick --------------B50B2D0290FD745AEF4A860F Content-Type: text/plain; charset=us-ascii; name="oops.txt" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="oops.txt" Jan 14 08:42:40 pegasus kernel: Unable to handle kernel paging request at virtual address 00300014 Jan 14 08:42:40 pegasus kernel: printing eip: Jan 14 08:42:40 pegasus kernel: c0147d2f Jan 14 08:42:40 pegasus kernel: *pde = 00000000 Jan 14 08:42:40 pegasus kernel: Oops: 0000 Jan 14 08:42:40 pegasus kernel: CPU: 0 Jan 14 08:42:40 pegasus kernel: EIP: 0010:[] Not tainted Jan 14 08:42:40 pegasus kernel: EFLAGS: 00010206 Jan 14 08:42:40 pegasus kernel: eax: 00300000 ebx: d82f0e78 ecx: df84de50 edx: d82f0e90 Jan 14 08:42:40 pegasus kernel: esi: d82f0e60 edi: d82f2440 ebp: 0000ba58 esp: c1955f30 Jan 14 08:42:40 pegasus kernel: ds: 0018 es: 0018 ss: 0018 Jan 14 08:42:40 pegasus kernel: Process kswapd (pid: 5, stackpage=c1955000) Jan 14 08:42:40 pegasus kernel: Stack: c012f67c dffe007c c1954000 ffffffff 000001d0 c0297b28 c1954000 00000000 Jan 14 08:42:40 pegasus kernel: 00000020 000001d0 00000006 00000006 c01480c0 0000bcfd c012f887 00000006 Jan 14 08:42:40 pegasus kernel: 000001d0 c0297b28 00000006 000001d0 c0297b28 00000000 c012f8ec 00000020 Jan 14 08:42:40 pegasus kernel: Call Trace: [] [] [] [] [] Jan 14 08:42:40 pegasus kernel: [] [] [] [] [] [] Jan 14 08:42:40 pegasus kernel: Jan 14 08:42:40 pegasus kernel: Code: 8b 40 14 85 c0 74 0a 57 56 ff d0 5a 59 eb 1a 89 f6 57 e8 4a Jan 14 08:42:47 pegasus kernel: <1>Unable to handle kernel NULL pointer dereference at virtual address 000001f8 --------------B50B2D0290FD745AEF4A860F Content-Type: text/plain; charset=us-ascii; name="trace.txt" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="trace.txt" ksymoops 2.4.3 on i686 2.4.17.

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.
