-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 So it has been a while and a lot of hair pulling but kload is sorta alive and kicking. It can now load the kernel from userspace, copy it over the running kernel and jump the the kernel entry point. I'm still having problems getting through the boot process due to interrupts arriving for unconfigured handlers. Fatal Trap (30) If anybody has some experience with acpi and interrupt configuration in general and is willing to help please let me know. - -Russell On 6/16/11 1:32 PM, Russell Cattelan wrote: > I have been contacted about possibly implementing a fast reboot > mechanism for FreeBSD similar to kexec on Linux. > > I have just started looking into how this accomplished so I figured > a note to freebsd hackers would also be a good place to ask for > comments. > > Has anybody looked at doing something like kexec? > > Is it the right thing to do for FreeBSD.
