grub bug at boot time: no symbol table
Posted: Wed Oct 25, 2017 7:30 am
OS: AntiX 17 32-bit, fresh install
Hardware:
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.
