I updated the module-init-tool to try 2.6-test2. When I installed module-init-tool, I did
so the insmod and depmod stuff became *.old.
After it's done, both 2.4 and 2.6 were working. Two weeks later, that's yesterday, I applied the 2.4.21-ck3 patch and recompiled my kernel. Then X is broken now. Error message:
Fatal server error:
xf86OpenConsole: Cannot open virtual console 7 (Input/output error)
What could be the possible cause?
