Hello Since a few days (seems that since 24 Mar) I am getting a lot of ld segfaults and general protection errors on one of my systems: Mar 31 08:16:16 belkin2 ld[12924]: segfault at 9 ip 00002af662155030 sp 00007fff4899b200 error 4 in libbfd-2.18.so[2af66210c000+c2000] Mar 31 08:17:30 belkin2 ld[13785]: segfault at 15 ip 00002b0c4f409030 sp 00007fff5b6e8f50 error 4 in libbfd-2.18.so[2b0c4f3c0000+c2000] Mar 31 08:17:39 belkin2 ld[14504]: segfault at 107 ip 00002ba111b63030 sp 00007fff98f8d800 error 4 in libbfd-2.18.so[2ba111b1a000+c2000] Mar 31 08:17:42 belkin2 ld[14736] general protection ip:2b3acb859b22 sp:7fffdf287d68 error:0 in libbfd-2.18.so[2b3acb821000+c2000] Mar 31 08:17:46 belkin2 ld[14952]: segfault at 107 ip 00002ab9ea7e4030 sp 00007fffc030b8f0 error 4 in libbfd-2.18.so[2ab9ea79b000+c2000] Mar 31 08:17:47 belkin2 ld[15019]: segfault at c5 ip 00002b685dbe8030 sp 00007fff4cf08770 error 4 in libbfd-2.18.so[2b685db9f000+c2000] Mar 31 08:41:19 belkin2 system 00:00: iomem range 0x7fef0000-0x7fefffff could not be reserved Mar 31 08:41:19 belkin2 abituguru: bank2 sensor 5 does not seem to be a fan sensor: the threshold (0) is below the minimum (5) Mar 31 08:41:19 belkin2 Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd, not after Mar 31 10:53:59 belkin2 system 00:00: iomem range 0x7fef0000-0x7fefffff could not be reserved Mar 31 10:53:59 belkin2 abituguru: bank2 sensor 5 does not seem to be a fan sensor: the threshold (0) is below the minimum (5) Mar 31 10:54:55 belkin2 ld[5044]: segfault at 107 ip 00002ba652b25030 sp 00007fff57fcd860 error 4 in libbfd-2.18.so[2ba652adc000+c2000] Mar 31 10:54:56 belkin2 ld[5060]: segfault at 107 ip 00002aacc5d16030 sp 00007fffe4dda670 error 4 in libbfd-2.18.so[2aacc5ccd000+c2000] Mar 31 11:27:50 belkin2 system 00:00: iomem range 0x7fef0000-0x7fefffff could not be reserved Mar 31 11:27:50 belkin2 abituguru: bank2 sensor 5 does not seem to be a fan sensor: the threshold (0) is below the minimum (5) Mar 31 11:28:40 belkin2 ld[4794]: segfault at f959010 ip 00002b01be86eb6b sp 00007fffec2a0300 error 4 in libbfd-2.18.so[2b01be808000+c2000] Mar 31 11:28:40 belkin2 ld[4802]: segfault at 95 ip 00002b7c84aba030 sp 00007fff260358d0 error 4 in libbfd-2.18.so[2b7c84a71000+c2000] Mar 31 11:37:31 belkin2 ld[15616]: segfault at 107 ip 00002ba3b9082030 sp 00007ffff1a701e0 error 4 in libbfd-2.18.so[2ba3b9039000+c2000] Mar 31 11:39:49 belkin2 ld[17375]: segfault at 107 ip 00002b1c4d8fe030 sp 00007fff5d1f3970 error 4 in libbfd-2.18.so[2b1c4d8b5000+c2000] Mar 31 11:39:50 belkin2 ld[17406] general protection ip:2b4d26595b6b I already know that this is usually a hardware related problem. But I have seen that I can reproduce the segfault very frequently when running "make menuconfig" on my kernel sources dir (yes, I have already tried to clean up completely sources dir but I get segfaults again just after running "make all" on it) As I thought it could be a hardware problem, I tried to install Mandriva 2009.0 on a different partition for trying to follow the same steps, but ld never segfaults under mandriva, even running "make menuconfig" on exactly the same sources dir copied from gentoo partition. Then, I have re-emerged binutils with -march=k8 -O2 -ggdb and added "split-debug" to the features for trying to get a proper backtrace from a generated core file. If I have missed something, please point me it for solving it. I am a bit worried because these ld segfaults cause a lot of merges to fail This emerge --info is from yesterday (you will see that still have old CFLAGS I use for all the system), but I have only modified CFLAGS and FEATURES for trying to get a proper backtrace as explained above Thanks a lot for your help Reproducible: Always

you'll have to start by finding a command you can run that'll always crash. running `make menuconfig` is not such a command. that rule implies compiling other files ... you'll have to find those commands that are being run and crashing.
With "ps axu | grep ld" seems that it's running the following: /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../x86_64-pc-linux-gnu/bin/ld --eh-frame-hdr -m elf_x86_64 -dynamic-linker /lib64/ld-linux-x86-64.so.2 -o /dev/null /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64/crt1.o /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64/crti.o /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/crtbegin.o -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2 -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2 -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../x86_64-pc-linux-gnu/lib -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../.. /tmp/ccqq6bJW.o -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/crtend.o /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64/crtn.o But I cannot run it manually because /tmp/ccqq6bJW.o seems to be erased after "make menuconfig" ends :-/
The same occur with "make oldconfig". Also, simply trying to compile eix sometimes will fail sooner or later due the same crash, but it takes a bit more tries to reproduce
`make V=1 ...` will show you all commands the kernel runs
(In reply to comment #7) > `make V=1 ...` will show you all commands the kernel runs > Finally I reinstalled system and problem disappeared :-), sadly, I didn't finally know what was messed up :-( But thanks a lot for the information :-)

The problem is that I don't know if something has broke recently or there is a bug in powernow_k8 or ondemand modules, since I were using ondemand since 2005 without any problems :-/
might want to file a bug at http://bugzilla.kernel.org/ ... they should be able to help you diagnosis the problem it would help them a lot if you could find a kernel release version that worked and one that did not
OK, I will follow your suggestion Thanks a lot for your attention
