PXELINUX: how to debug initrd corruption?
...cause of
the initrd image corruption?
I've examined the TFTP transfers with Wireshark; they appear OK.
I have not tried a more modern pxelinux.0 yet.
2. Can anyone provide a description or simple diagram of what regions of
system memory PXELINUX uses?
>From the linker file, I know that .earlybss starts at 0x800 (or 0x1000),
and a number of sections directly follow it.
I also realize some allocated regions are system specific, depending on
what the BIOS returns in its E820 map.
I am, not surprisingly, interested in the regions where PXELINUX stores
the kernel and initramdisk images after TF...

[PATCH 0/4] Improve linker scripts
From: Sylvain Gault <sylvain.gault at gmail.com>
These patches basically remove unused linker scripts and port a change that was
made to an unused script.
Those are to be applied on top of the gcc 5 bug fixes as they would conflict
otherwise.

diag/mbr: fix dependency to linker script
Remove unused linker scripts
core: Make symbols defined in linker script HIDDEN

[PATCH 0/9] elflink fixes
From: Matt Fleming <matt.fleming at intel.com>
Here are the patches that I've got queued up based on the very helpful
feedback I received from people testing Syslinux 5.00-pre9. Unless
anyone has any concerns these will make it into Syslinux 5.00-pre10.
Matt Fleming (9):
pxe: Don't call open_config() from the pxe core
ldlinux: Print a warning if no config file is found
