Unable to handle kernel paging request

[sawik]

Hey!

I've got Asus wl-500gpv1 and performed RAM upgrade on it (now i have 128MB).

When I power up my router, openwrt loads and everything seems to be ok, but a few minutes later i get such message on console (direct connect to PCB, ttyS0):

[  165.040000] Disabling lock debugging due to kernel taint

could you help me? what's wrong?

[wpte]

usually you get errors like that when you have faulty ram...
so perhaps the chip you desoldered and soldered became to hot and is faulty now...
seems a reasonable explanation I think

[sawik]

Thank you for the answer.

After Christmas i'll try to solder another chips and we'll see if it's a reason.

Merry Christmas
