Hello
I 'm trying to boot my fresh l4linux, i used the following entry in grub as adam previously told me to.
title L4/Linux root (hd0,0) kernel /l4linux/rmgr -sigma0 task modname "L4Linux task" task modname "bmodfs" module module module modaddr 0x02000000 module /l4linux/fiasco -nowait -nokdb -serial_esc -comspeed 115200 -comport 1 module /l4linux/sigma0 module /l4linux/names module /l4linux/log module /l4linux/dm_phys module /l4linux/simple_ts -t 300 module /l4linux/l4io --noirq module /l4linux/bmodfs module /l4linux/libloader.s.so module /l4linux/run-l4 module /l4linux/vmlinuz26 module /l4linux/l4exec module /l4linux/loader --fprov=BMODFS run-l4
It starts but i get the following error messages :
simplets|configured for 300 tasks bmodfs | L4RM: [PF] read at 0x00000000, eip 0122c495, src A.01 bmodfs | [A.0] l4rm/lib/src/pagefault.c:78:__unknowm_pf(): bmodfs | unhandled page fault
It seems to be a problem with a null pointer and i'm sure it is a problem in my grub file but i don't know what's wrong. I tried to change some options but i always get this problem but it is not always the same server that crashes, it depends on my options.
This bug report lacks of many information. Please start with debugging at the faulting eip: Press the ESC key and type
uta<space>122c495<space
You will (hopyfully) see a disassembler listing. If there are line numbers included into the listing, fine. If not, disassemble your bmodfs with
objdump -ld bmodfs | less
and search for the faulting eip. You have to find out the relation between the faulting eip and the source line.
