May em dung FC2, hom bua dang xa`i nu*?a chu`ng thi. bi. ddu*'ng, treo
ma'y luon nen phai reset ma'y. The^' la` sau khi reboot FC cu?a em co'
va^'n de^` ngay.
Nhu* mo.i khi, sau khi load kernel no' tha^'y la partition chua duoc
umount hoa`n toa`n ne^n ca^`n check la.i. Em ok va` cha.y fsck cho ca? 3
partition cua FC (/root, /home va` /usr). Sau khi check xong kho^ng
the^? va`o GUI duoc (Gnome) vo*'i ly' do la` : "Init: id x respawning
too fast: disabled for 5 minutes". Sau khi google va^~n chu* ca?i
thie^.n ti`nh hi`nh la` ma^'y
Em xin no'i ti`nh hi`nh tra.ng truo'c ro^`i mo*'i ddu*a ra va`i pha^`n

Cha('c la do cha.y file .bashrc hay gi` do'.
Va^'n de^` cu?a em o*? da^y la`: root partition bi mount la readonly
