Since QEMU is a popular subject lately, I think I'll bring up one more issue. When booting FreeBSD (-CURRENT in this case) in a QEMU session (with or without any kqemu), it nearly always hangs at the loader countdown screen, somewhere in the 1-10 seconds it takes to countdown. When it hangs, it spins doing: [..snip..] 3216 qemu CALL clock_gettime(0x4,0xbfbfb048) 3216 qemu RET clock_gettime 0 3216 qemu CALL sigreturn(0xbfbfb0b0) 3216 qemu RET sigreturn JUSTRETURN 3216 qemu CALL sigprocmask(SIG_SETMASK,0xbfbfb360,0) 3216 qemu RET sigprocmask 0 3216 qemu CALL sigprocmask(SIG_BLOCK,0,0x28669288) 3216 qemu RET sigprocmask 0 3216 qemu CALL select(0xa,0xbfbfb3c0,0xbfbfb340,0xbfbfb2c0,0xbfbfb2b8) 3216 qemu RET select 0 3216 qemu CALL clock_gettime(0x4,0xbfbfb278) 3216 qemu RET clock_gettime 0 3216 qemu CALL clock_gettime(0x4,0xbfbfb218) 3216 qemu RET clock_gettime 0 3216 qemu CALL clock_gettime(0x4,0xbfbfb278) 3216 qemu RET clock_gettime 0 3216 qemu CALL sigprocmask(SIG_BLOCK,0,0x28669288) 3216 qemu RET sigprocmask 0 3216 qemu PSIG SIGALRM caught handler=0x804bf14 mask=0x0 code=0x0 3216 qemu CALL clock_gettime(0x4,0xbfbfb048) 3216 qemu RET clock_gettime 0 3216 qemu CALL sigreturn(0xbfbfb0b0) 3216 qemu RET sigreturn JUSTRETURN [..repeats forever..] In the QEMU console, if I press a key it will break the loop and move on just fine. The only problem is that I can't have auto-started qemu FreeBSD systems, since it requires a keystroke to boot it up. Anyone have any ideas on this? I can test any patches, and do whatever debugging someone whats to point me to. Side note: Windows qemu sessions do not do this, and FreeBSD boots that do not use the loader software also don't do it if I recall correctly. Eric
