Hi,
For daily kernel testing, I (try to) use kexec to boot each new kernel.
This hasn't been working for several weeks now.
A "git bisect" only pointed me at one of Arjan's async boot (fastboot)
patches, but he and I think that's a git bisect anomaly.
The test system is an HP BladeCenter 4-proc with 8 GB of RAM
(HP BladeCenter BL c-class: ProLiant BL685c G1).
It boots from an HP/Compaq CCISS drive (using an initramfs).
I capture the kernel log via netconsole, so sometimes the last few
lines of the kernel log are lost. This is what the end of the
netconsole capture looks like:

[more of the kernel log including above is available at
http://oss.oracle.com/kerneltest/logs/netcon-5975.log, but it does not include
the beginning of the kernel boot for some reason -- it was truncated]
and this is what is on the serial console output (which I don't know how
to capture in its entirety):

Can anyone suggest other tests to try?
