Hi anyone.
Tot in kernel oops-ul ma zbat de ceva timp bun...
Orice sugestie e binevenita si multumesc anticipat.
Ce am in ksyms (simbolurile exportate din kernel):
------------------------------------------------------------------------------------------
Address Symbol Defined by
c481c060 __insmod_tema1_S.text_L528 [tema1]
c481c1d8 my_sys_exit [tema1]
c481c8f8 original_sys_exit [tema1]
c481c0b0 my_syscall [tema1]
c481c060 my_interceptor [tema1]
c481c1ec my_module_init [tema1]
c481c000 __insmod_tema1_O/mnt/vmshare/tema1/tema1.o_M4064959E_V132121 [tema1]
c481c4c0 __insmod_tema1_S.bss_L1088 [tema1]
c481c4c0 original_call_table [tema1]
c481c280 __insmod_tema1_S.rodata_L224 [tema1]
c481c234 my_module_exit [tema1]
c4811000 __insmod_smbfs_O/lib/modules/2.4.25/kernel/fs/smbfs/smbfs.o_M4049542D_V132121
[smbfs]
c4811060 __insmod_smbfs_S.text_L29440 [smbfs]
c48183a0 __insmod_smbfs_S.rodata_L5984 [smbfs]
c4819c00 __insmod_smbfs_S.data_L1216 [smbfs]

Dupa ce am trecut oops-ul prin ksymoops, am obtinut:
------------------------------------------------------------------------------------------
