Has anybody managed to get IBM's jdk 1.1.8 for linux working? http://www.ibm.com/java/jdk/118/linux/index.html It features "native" threads via linux threads and a JIT. When I attempt to run it on a machine with a -current kernel and linux module, and linux_base 6.1, I see: /compat/linux/usr/jdk118/bin/appletviewer sigaltstack: Cannot allocate memory sigaltstack: Cannot allocate memory Meanwhile on the console, I see: kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 9 with interrupts disabled kernel trap 12 with interrupts disabled <.....> forever A linux ktrace of the area around the error messages shows: 1780 java CALL linux_modify_ldt(0x11,0xbfbff2a8,0x10) 1780 java RET linux_modify_ldt 0 1780 java CALL linux_rt_sigaction(0xa,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0xb,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0x4,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0x8,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0x7,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0x6,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0x3,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigaction(0xd,0xbfbff158,0xbfbff0cc,0x8) 1780 java RET linux_rt_sigaction 0 1780 java CALL linux_rt_sigprocmask(0x1,0x281f9380,0,0x8) 1780 java RET linux_rt_sigprocmask 0 1780 java CALL linux_brk(0x8057000) 1780 java RET linux_brk 134574080/0x8057000 1780 java CALL linux_modify_ldt(0x11,0xbfbff29c,0x10) 1780 java RET linux_modify_ldt 1 1780 java CALL linux_sigaltstack(0xbfbff290,0) 1780 java RET linux_sigaltstack -1 errno 12 Cannot allocate memory 1780 java CALL write(0x2,0xbfbfc798,0x24) 1780 java GIO fd 2 wrote 36 bytes "sigaltstack: Cannot allocate memory " 1780 java RET write 36/0x24 1780 java CALL mprotect(0xbfbe0000,0x1000,0) 1780 java RET mprotect 0 1780 java CALL linux_open(0x281f0f40,0x2,0xbfbff414) 1780 java NAMI "/compat/linux/dev/zero" 1780 java NAMI "/dev/zero" 1780 java RET linux_open 3 <...> The sigaltstack messages seem to be caused by lss.ss_size = 0x800 which is < our MINSIGSTKSZ.

I'm more an alpha hacker than an i386 hacker and I have no clue what the trap 9 messages mean.
