Since nobody here seems to be able to figure it out... I wrote a program to
play around with aio_read(), and it ran stellarly well on my
FreeBSD3.4-release system using EIDE hard drives. But, when I tried to run
it on a system using our production kernel with Adaptec SCSI controllers,
it locked the kernel up HARD. No console messages, no Ctrl-Alt-Del, had to
push the hard reset switch.
The kernel in question is a FreeBSD3.4-release kernel compiled with a
different set of options (lots of mbufs, etc, etc). I can't find anything
in it that seems at all related to async I/O. The appropriate sysctl
values all seem the same between the systems. And the fact that it locks
the system up instead of saying ENOTSUPP or "async I/O not compiled in"
concerns me greatly.
Any ideas on why this might be happening?
Thanks much,
scott
