I have a C2811 router with 12.4.15(t10) IOS at a remote site which failed to reboot after a power cycling . I directed the on site tech to replace the flash card and reboot, and router recovered no problems. I wanted to look at the "bad" card and requested the tech re insert this card. As I executed a dir command, the router froze up and again had to be recovered using the spare flash card. Any ideas about what could be causing this behavior? Thanks
I have this problem too.
