Hi all,

To stress a bit kernel I launch my usual loop test on the n4k (2way, 4Gb ram):
# while true ; do readprofile -r ; make $OPTB clean ; make $OPTB oldconfig; make -j2 $OPTB vmlinux 2>&1 | tee -a /var/logs/k-loop; 
readprofile >> /var/logs/prof-loop.doc ; done

With previous kernel it makes panic kernel hazardiously from 1 to more 200 occurences. With this 2.6.11-rc3-pa3 after about 49 runs 
some "Segmentation fault" occures:
make[3]: *** [drivers/pci/probe.o] Segmentation fault
make[3]: *** [drivers/block/ioctl.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/fpudispatch.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/driver.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/driver.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/frnd.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/driver.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/denormal.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/frnd.o] Segmentation fault
make[3]: *** [drivers/md/raid0.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/driver.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/driver.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/frnd.o] Segmentation fault
make[2]: *** [arch/parisc/math-emu/frnd.o] Segmentation fault

for some child's shell (I attached dmesg because very long).

I so stop this loop to reboot with same kernel but up build and relaunch the loop.
After about 12h it already runs 80 times without any segmantation fault.

Any idea?

Thanks,
     Joel

PS: this last was build with gcc-3.3-hppa64 and binutils-hppa64 while previous was build with hppa64-gcc-3.0 and same binutils
