Things I've seen so far.. - long running tasks SIGINT, even though I wasn't even anywhere near the keyboard. - processes running inside screen/tmux disappearing (and taking the whole session with them). And now, while waiting for a kernel to build I just saw.. /bin/sh: line 1: 3274 Hangup gcc -Wp,-MD,net/netfilter/.xt_HL.o.d -nostdinc -isystem /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include -I/home/davej/src/linux-dj/arch/x86/include -Iarch/x86/include/generated -Iinclude -include /home/davej/src/linux-dj/include/linux/kconfig.h -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-delete-null-pointer-checks -O2 -m64 -mtune=generic -mno-red-zone -mcmodel=kernel -funit-at-a-time -maccumulate-outgoing-args -fstack-protector -DCONFIG_X86_X32_ABI -DCONFIG_AS_CFI=1 -DCONFIG_AS_CFI_SIGNAL_FRAME=1 -DCONFIG_AS_CFI_SECTIONS=1 -DCONFIG_AS_FXSAVEQ=1 -DCONFIG_AS_AVX=1 -pipe -Wno-sign-compare -fno-asynchronous-unwind-tables -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -Wframe-larger-than=2048 -Wno-unused-but-set-variable -fno-omit-frame-pointer -fno-optimize-sibling-calls -g -pg -Wdeclaration-after-statement -Wno-pointer-sign -fno-strict-overflow -fconserve-stack -DCC_HAVE_ASM_GOTO -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(xt_HL)" -D"KBUILD_MODNAME=KBUILD_STR(xt_HL)" -c -o net/netfilter/xt_HL.o net/netfilter/xt_HL.c Any thoughts on specific commits that might be guilty ?
