Thanks. ----- Additional Comments From moilanen.com(prefers email via moilanen.com) 2004-12-14 14:47 EDT ------- DEBUG_SLAB is a config option under: Kernel Hacking -> Debug memory allocations ----- Additional Comments From salina.com 2004-12-14 16:01 EDT ------- Carlos, reboot the machine. I rebuild kernel for you. ----- Additional Comments From salina.com 2004-12-14 16:02 EDT ------- Jake, You want to use this kernel or latest David Howell kernel ? ----- Additional Comments From ameet.com 2004-12-14 16:14 EDT -------
I did some disassembly. I could not objdump the entire trace, so I had to use
the one provided by xmon.
In hash_page function,
read_lock(&pte_hash_lock[smp_processor_id()]); <--this is instr ldx
r0,r9,r6
ptep = find_linux_pte(pgdir, ea);
/*
* If no pte found or not present, send the problem up to
* do_page_fault
*/
if (ptep && pte_present(*ptep)) <--- this is cmpdi cr7,r6,0.
{
ret = __hash_page(ea, access, vsid, ptep);
} else {
/* If no pte, send the problem up to do_page_fault */
ret = 1; <--- Going with Jake's comment, I think it fails
here.
}

#define pte_present(pte) (pte_val(pte) & (_PAGE_P | _PAGE_PROTNONE))
#define pte_val(x) ((x).pte)

----- Additional Comments From scarlos.com 2004-12-14 17:18 EDT ------- SDET script You can run this script with the new kernel. to try and recreate. ----- Additional Comments From scarlos.com 2004-12-14 17:19 EDT ------- SDET completed successfully on Power 4 650 box hostname: ppc64hlp6.ltc.austin.ibm.com ip: 9.3.190.136 uid: root pwd: .pasroot ----- Additional Comments From scarlos.com 2004-12-14 17:31 EDT ------- The test was successful on power 4 650 and power 5 HV2 on RHEL4 pre-RC1 ----- Additional Comments From scarlos.com 2004-12-14 17:40 EDT ------- Steps to run SDET: 1. mkdir /skyline 2. mount 9.3.192.95:/home/public /skyline 3. ./FVTR_SDET.sh ----- Additional Comments From robbiew.com 2004-12-14 17:47 EDT ------- This test passed on a Power4 AND an HV2 (Power5) with a higher version of firmware. We will flash this particular SF2 to the same level and attempt a recreate. ----- Additional Comments From khoa.com 2004-12-14 18:26 EDT ------- Until we know more about this problem, I'd like to keep this bug in HIGH severity. If this turns out to be a true data corruption/miscompare problem, we would need to bump the severity up at that point. Thanks. ----- Additional Comments From salina.com 2004-12-14 19:05 EDT ------- Carlos udpated firmware.. SDET restarted. Robbie will keep track and update. Erm, IBM people - this bug number is for a "hostnames as wallpaper" request, not a kernel bug.. Uhm? What the heck? Glen: Why are you adding some kernel stuff to this bug? ----- Additional Comments From robbiew.com 2004-12-15 11:30 EDT ------- Test Run Update - The test is still running and the machine is still up and responsive. :) ----- Additional Comments From robbiew.com 2004-12-15 16:31 EDT ------- Test update - Still running with no problems. ----- Additional Comments From robbiew.com 2004-12-16 11:00 EDT ------- Testing completed without problems. ----- Additional Comments From mjwolf.com 2004-12-16 12:15 EDT ------- testing completed on the FW that originally exhibited the problem or the updated FW? If the tests completed on the updated FW, please put the 'older' FW on and re-run the test. Want to make sure this problem can be recreated. ----- Additional Comments From robbiew.com 2004-12-16 12:22 EDT ------- It completed with the new FW. Comment #28 stated that the tester was able to recreate twice on the older FW. What do we gain by going back to the older FW and recreating for a third time? ----- Additional Comments From scheel.com 2004-12-16 14:16 EDT ------- We need root cause for this defect, even if it means going back to old firmware. ----- Additional Comments From robbiew.com 2004-12-17 11:10 EDT ------- I flashed the machine to the oldest firmware available from the firmware download site...and the test still passed. I was put in contact with someone who can get the actual old level I need (b0824a_0434.220). As soon as I receive this level, I will flash and re-test. ----- Additional Comments From robbiew.com 2004-12-17 13:01 EDT ------- I've flashed to b0824a_0434.220 and will update on the status of the recreate attempt. ----- Additional Comments From robbiew.com 2004-12-20 10:55 EDT ------- Ran the test for the full 24 hours with b0824a_0434.220 and no recreate. I think all we can do now is close as unreproducible. ----- Additional Comments From robbiew.com 2004-12-20 11:04 EDT ------- Closing as unreproducible. We will run this again on the next RC2 (12/20) release, on this same machine and firmware...to make sure. ----- Additional Comments From moilanen.com(prefers email via moilanen.com) 2005-01-10 10:47 EST ------- Reclosing as unreproducable. Please reopen if it's hit again. changed:
