grub bug at boot time: no symbol table

#1 Postby greenpossum » Wed Oct 25, 2017 7:30 am

OS: AntiX 17 32-bit, fresh install


1. Asus EEE PC 900, 32-bit, 1GB RAM, 8 GB disk
2. VirtualBox 32-bit, 1GB RAM, 8 GB disk

What happens: On power up, grub flashes a message saying "no symbol table" before showing the graphical boot menu. After selecting AntiX, it again shows "no symbol table", and a couple of lines later Press any key to continue. If a key is pressed or one waits a few seconds, the boot will continue as normal.

This appears to be an upstream bug in grub, a search on the phrase "grub error no symbol table" shows that this happens in many distros. However this Debian bug report seems to be the most informative:

https://bugs.debian.org/cgi-bin/bugrepo ... bug=841297

Even though it mentions grub-efi it happens with other boot loaders too, as the search results show. Also this bug seems to have been there perhaps a year or two, and the latest report from a couple of months ago has no solution. The best clue I think is that the load video line in grub.cfg triggers it and perhaps one of the video modules doesn't have symbols.

I first happened on this bug when I tried to fix the warning that vga= was deprecated in favour of gfxpayload but the bug also happens with vga= I tried the suggested fixes in posts, grub-install, update-grub, etc. to no avail.

Although it's just an annoyance slowing down boot, it would be nice if someone could hunt down the bug and take the glory. Debugging grub is a bit beyond me unfortunately.

Cheers and thanks for AntiX, it's just the thing for my ancient netbook. :happy:

I ran AntiX for years on EEEPC 900's and wrote tutorials on just that hardware. Virtual Box running on EEEPC 900 with a 800 MHZ celeron processor?

That is not my territory. I would never even think of doing that . Even on my current Single core atom n270 9 inch net-book with a touch screen and 2 gig of ram with a 60 gig SSD drive. Which I replaced my EEEPC's with.

Back then. I ran legacy grub. Now. With 16.2 presently on my touch screen net-book. Which uses grub2. Still no problemo with a regular install. So I think they may be a virtual box setup problem of some sort. Which I am not qualified to answer on.

Later on < in the future >. I will be reinstalling AntiX < 17 Stretch version > on my touch screen net-book. Just procrastinating because of my touch screen hardware. Because I use a little elbow grease to set that up.

Good luck with it. Sorry I am not qualified to trouble shoot this.

Edit. Read your bug report after I posted. Maybe a Debian Stretch bug you found about. I guess I'll find out when I reinstall AntiX on my net-book.

Yes, you read it correctly eventually. It happens on both platforms, real and virtual. And it happens in other distros too so I think it's a grub bug, possibly due to some change in the toolchain used to build grub. Good luck with your install.

For the benefit of others as well, I found that unetbootin doesn't create a suitable USB stick but the live USB builder in AntiX 17 does. So I built the USB stick for my netbook using the virtual AntiX 17 writing to the USB stick using USB passthrough (great feature).

Return to “antiX”
