Hi,
recently I have tried to build picobsd image for a different
architecture than the current one, with only partial success.
In particular, three weeks ago i committed some changes to the
picobsd script so now i can build working amd64 images on amd64.
However when i try a cross build (e.g. i386 image on an amd64 host)
the kernel stops right after trying to mount the root partition.
The error message is the following:
...
Timecounter "TSC" frequency 1858691100 Hz quality 800
Trying to mount root from ufs:/dev/md0 []...
panic: mutex Giant owned at .../sys/kern/kern_exit.c:128
cpuid = 0
KDB: enter: panic
[ thread pid 1 tid 100001 ]
Stopped at kdb_enter+0x3b: movl $0,kdb_why
db>
The backtrace indicates the following (i omit the numbers, as
i am manually copying the text)
kdb_enter
panic
_mtx_assert
exit1
kern_execve
sys_execve
exec_shell_imgact
fork_exit
fork_trampoline
--- trap 0, eip = 0, esp = 0xc3708d60, ebp = 0 ---
any idea on what could be going wrong ?
On a related topic, does anyone have experience on cross-building
nanobsd images ?
thanks
luigi
