[afnog] Cisco7606 boot failure

[Mathias HOUNGBO]

Hi Miku

this error : compressed image checksum is incorrect 0x95E93FF2 Expected
a checksum of 0xF4C5466F
means that the IOS on the flash is not good ! perhaps the flash is diying ?

and a stupid question : are you check the free space available on the
flash ?
