I always use the same .config After I try gentoo-sources-2.6.34 and vanilla-sources-2.6.34 but the problem remain, the compile freeze and I see this in ps -elf: 5 S root 1013 1 0 76 -4 - 3125 poll_s 13:00 ? 00:00:00 /sbin/udevd --daemon 1 S root 2669 1 0 80 0 - 7523 wait 13:00 ? 00:00:00 supervising syslog-ng 5 S root 2670 2669 0 80 0 - 7556 poll_s 13:00 ? 00:00:00 /usr/sbin/syslog-ng 1 S root 3258 1 0 80 0 - 9505 poll_s 13:00 ? 00:00:00 /usr/sbin/sshd 1 S root 3378 1 0 80 0 - 4115 hrtime 13:00 ? 00:00:00 /usr/sbin/cron 0 S root 3446 1 0 80 0 - 1493 n_tty_ 13:00 tty2 00:00:00 /sbin/agetty 38400 tty2 linux 0 S root 3447 1 0 80 0 - 1493 n_tty_ 13:00 tty3 00:00:00 /sbin/agetty 38400 tty3 linux 0 S root 3448 1 0 80 0 - 1493 n_tty_ 13:00 tty4 00:00:00 /sbin/agetty 38400 tty4 linux 0 S root 3449 1 0 80 0 - 1493 n_tty_ 13:00 tty5 00:00:00 /sbin/agetty 38400 tty5 linux 0 S root 3450 1 0 80 0 - 1493 n_tty_ 13:00 tty6 00:00:00 /sbin/agetty 38400 tty6 linux 5 S root 3457 1 0 80 0 - 5959 poll_s 13:00 ? 00:00:00 SCREEN -S sb1 4 S root 3458 3457 0 80 0 - 4454 wait 13:00 pts/0 00:00:00 -/bin/bash 4 S root 3462 3458 0 75 -5 - 45171 poll_s 13:00 pts/0 00:00:34 /usr/bin/python2.6 /usr/bin/emerge -e world 4 S root 3613 1 0 80 0 - 14014 wait 13:01 tty1 00:00:00 /bin/login -- 4 S root 3953 3613 0 80 0 - 4429 n_tty_ 13:01 tty1 00:00:00 -bash 0 S root 6614 3462 0 75 -5 - 972 wait 14:26 pts/0 00:00:00 [dev-util/pkgconfig-0.23] sandbox "/usr/lib64/portage/bin/ebuild.sh" compile 4 S root 6615 6614 0 75 -5 - 6362 wait 14:26 pts/0 00:00:00 /bin/bash /usr/lib64/portage/bin/ebuild.sh compile 5 S root 6646 6615 0 75 -5 - 6745 wait 14:26 pts/0 00:00:00 /bin/bash /usr/lib64/portage/bin/ebuild.sh compile 4 S root 13235 6646 0 75 -5 - 3651 wait 14:27 pts/0 00:00:00 make -j8 4 S root 13238 13235 0 75 -5 - 3652 wait 14:27 pts/0 00:00:00 make all-recursive 4 S root 13239 13238 0 75 -5 - 5956 wait 14:27 pts/0 00:00:00 /bin/sh -c set fnord $MAKEFLAGS; amf=$2; \?dot_seen=no; \?target=`echo all-recursive | sed s/-recursive//`; \?list= 5 S root 13243 13239 0 75 -5 - 5956 wait 14:27 pts/0 00:00:00 /bin/sh -c set fnord $MAKEFLAGS; amf=$2; \?dot_seen=no; \?target=`echo all-recursive | sed s/-recursive//`; \?list= 4 S root 13244 13243 0 75 -5 - 3686 wait 14:27 pts/0 00:00:00 make all 4 S root 13358 13244 0 75 -5 - 3684 wait 14:27 pts/0 00:00:00 make all-recursive 4 S root 13359 13358 0 75 -5 - 5956 wait 14:27 pts/0 00:00:00 /bin/sh -c set fnord $MAKEFLAGS; amf=$2; \?dot_seen=no; \?target=`echo all-recursive | sed s/-recursive//`; \?list= 5 S root 16546 13359 0 75 -5 - 5956 wait 14:28 pts/0 00:00:00 /bin/sh -c set fnord $MAKEFLAGS; amf=$2; \?dot_seen=no; \?target=`echo all-recursive | sed s/-recursive//`; \?list= 4 S root 16547 16546 0 75 -5 - 3652 wait 14:28 pts/0 00:00:00 make all 4 S root 16548 16547 0 75 -5 - 3652 n_tty_ 14:28 pts/0 00:00:00 make all-am 4 S root 16599 3258 0 80 0 - 17937 poll_s 15:07 ? 00:00:00 sshd: root@pts/2 4 S root 16602 16599 0 80 0 - 4429 wait 15:07 pts/2 00:00:00 -bash 4 R root 16611 16602 0 80 0 - 3698 - 15:08 pts/2 00:00:00 ps -elf 1 S root 31506 2 0 80 0 - 0 bdi_wr 14:25 ? 00:00:00 [flush-253:0] All in wait? After this test I reboot in 2.6.31-r10 and I complete emerge -e world succefully. The problem show always with all kernels >=2.6.32 I have setup something wrong in kernel? I post the .config in the previous email.
