Building world failed for me with: cc -O2 -pipe -Wall -Wmissing-prototypes -Wno-uninitialized -Wstrict-prototypes -I/usr/src/sbin/pfctl/../../contrib/pf/pfctl -DE k-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k -Wno-uninitialized -Wno-pointer-sign -c /usr/src/sbin/pfctl/../../sys f_ruleset.c In file included from /usr/src/sbin/pfctl/../../sys/contrib/pf/net/pf_ruleset.c:48: /usr/obj/usr/src/tmp/usr/include/sys/mbuf.h:131: error: expected specifier-qualifier-list before 'uma_zone_t' *** Error code 1 Stop in /usr/src/sbin/pfctl. *** Error code 1 Stop in /usr/src/sbin. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. Manually building from /usr/src/sbin worked, though. After resuming with make buildworld NO_CLEAN=YES, the next failure was: ===> usr.bin/netstat (all) cc -O2 -pipe -fno-strict-aliasing -DIPSEC -DSCTP -DINET6 -DNETGRAPH -DIPX -fstack-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Wno-pointer-sign -c /usr/src/usr.bin/netstat/if.c cc -O2 -pipe -fno-strict-aliasing -DIPSEC -DSCTP -DINET6 -DNETGRAPH -DIPX -fstack-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Wno-pointer-sign -c /usr/src/usr.bin/netstat/inet.c cc -O2 -pipe -fno-strict-aliasing -DIPSEC -DSCTP -DINET6 -DNETGRAPH -DIPX -fstack-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Wno-pointer-sign -c /usr/src/usr.bin/netstat/main.c cc -O2 -pipe -fno-strict-aliasing -DIPSEC -DSCTP -DINET6 -DNETGRAPH -DIPX -fstack-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Wno-pointer-sign -c /usr/src/usr.bin/netstat/mbuf.c In file included from /usr/src/usr.bin/netstat/mbuf.c:46: /usr/obj/usr/src/tmp/usr/include/sys/mbuf.h:131: error: expected specifier-qualifier-list before 'uma_zone_t' *** Error code 1 Stop in /usr/src/usr.bin/netstat. *** Error code 1 Stop in /usr/src/usr.bin. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. Again building from /usr/src/usr.bin worked. Resuming stopped with yet another similar error message but afterwards make buildworld NO_CLEAN=YES finished successfully. I haven't really investigated the problem yet, but it might have something to do with my make flags: f...@tp51 ~ $grep NO_ /etc/make.conf NO_BLUETOOTH= # do not build Bluetooth related stuff NO_FORTRAN= # do not build g77 and related libraries NO_I4B= # do not build isdn4bsd package NO_INET6= # do not build IPv6 related programs and libraries NO_IPFILTER= # do not build IP Filter package NO_KERBEROS= # do not build and install Kerberos 5 (KTH Heimdal) NO_LPR= # do not build lpr and related programs NO_MAILWRAPPER= # do not build the mailwrapper(8) MTA selector #NO_NIS= # do not build NIS support and related programs. NO_ATM=yes NO_VINUM=yes NO_OBJC=yes NO_SHAREDOCS=yes NO_PROFILE=yes NO_PORTDOCS=yes Commenting out the NO_INET6 line didn't make a difference. I'm using your patch on an IBM ThinPad R51 since three days and didn't notice any problems so far. I also briefly tested it on an AMD64 system but as sound stopped working I reverted to the old kernel after verifying that ssh worked. This is a snd_emu10kx(4) problem, though. Fabian
