When the gcov patches are applied to the kernels over the x86_64 machines, the kernel seg-faults during the bootup, Linux version 2.6.24-gcov-autokern1 (root@bl6-13.ltc.austin.ibm.com) (gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)) #1 SMP Fri Apr 4 13:15:01 CDT 2008 Command line: ro root=/dev/VolGroup00/LogVol00 console=tty0 console=ttyS1,19200 selinux=no autobench_args: root=/dev/mapper/VolGroup00-LogVol00 ABAT:1207333349 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009d400 (usable) BIOS-e820: 000000000009d400 - 00000000000a0000 (reserved) . . . . powernow-k8: Found 1 Dual Core AMD Opteron(tm) Processor 270 processors (4 cpu cores) (version 2.20.00) powernow-k8: MP systems not supported by PSB BIOS structure powernow-k8: MP systems not supported by PSB BIOS structure powernow-k8: MP systems not supported by PSB BIOS structure powernow-k8: MP systems not supported by PSB BIOS structure Freeing unused kernel memory: 456k freed Red Hat nash verinit[1]: segfault at ffffffff80ceccd8 rip ffffffffff60040c rsp 7fff05e68290 error 7 sion 5.0.32 starKernel panic - not syncing: Attempted to kill init! ting Please let me know, If any other information is reaquired. > > Regards-- > Subrata > > On Mon, 2008-04-21 at 14:22 +0530, Subrata Modak wrote: >> Hi, >> >> GCOV-kernel patches for Linux 2.6.25 are now available for downloads >> at: >> >> http://ltp.cvs.sourceforge.net/ltp/utils/analysis/gcov-kernel/, >> >> You can use them for generating code coverage on 2.6,25. >> >> -- >> Regards & Thanks-- >> Subrata >> ------------------------------------------------------------------------- >> This SF.net email is sponsored by the 2008 JavaOne(SM) Conference >> Don't miss this year's exciting event.
