[syslinux] EFI: HP + syslinux = crash [ brown paper bag update ]
Updating myself again: On 07-08-15 16:03, Oscar Roozen wrote: > e466d24 still has an issue with png's in vesalinux causing crashes I can confirm this remaining crash is caused by the line "MENU BACKGROUND bootlogo.png". The original bootlogo.png is 640x480. Forcing the videomode with "MENU RESOLUTION 640 480" did not resolve the crashes, nor did resizing the png to 1024x768 and forcing the mode to that size. If anyone wants to test or just admire this exact bootlogo.png, it is available for download at https://okkie.nu/tmp/bootlogo.png. What did work, was resaving the logo as a jpg. This boots just fine. According to the debug info, both videomodes initialized okay. The crash happens later.

The kernel line only appears after I select a menu entry of course. For me this has a very low priority, as the jpg workaround is just fine. But maybe somebody wants to dig deeper, just bug me if you want more feedback. > Is it time to update the official repository yet? ;-) Yeah! Found it at git://repo.or.cz/syslinux.git :-)

[syslinux] What about other patches? WAS: EFI: HP + syslinux = crash [ brown paper bag update ]
> > For me this has a very low priority, as the jpg workaround is just fine.Well, vesamenu.c32 under UEFI, although "almost needed", it is already behaving in a crappy manner anyway :(. (Reminder, FWIW, PNG is non-patented, loss-less and popular.) With so many regressions and features not working (in vesamenu under UEFI), I have "suggested" in past months / emails that perhaps it might need to (or should?) be reviewed altogether (maybe even improving it for BIOS too ;). In the meantime, perhaps some suggested patches (regarding other issues) might deserve some attention / not-so-low priority? Recent examples: _ com32: write_sectors fixes http://www.syslinux.org/archives/2015-August/023962.html _ efi: leaving long mode in kernel_jump routine http://www.syslinux.org/archives/2015-August/023911.html (Somewhat self-centered, but not so much: I would also like to see the initial patches from Patrick about the CLI and lss16 being taken by someone so to improve them, after 3 years of patiently waiting.) To be clear, I do not know their effects nor whether they are correct, needed, useful, convenient, positive... I am just hoping for them not to be ignored / left as "lost" in the mailing list. TIA, Ady.

This is a weird bug affecting zlib but it looks like a compiler issue (v4.7.2) Please implement these new changes over your last non-debug working build (multi-nic fix) and let's see how it goes. https://github.com/ppatpat/syslinux/compare/master...ppatpat:zlib?expand=1 Please report your results. Thanks, Best, Patrick

They are very good. No crashing even with the original config!
