Writing crashinfo to flash:crashinfo_20070817-161819
On the first fail, I reloaded the device and- bang- the flash: wasn't readable anymore !
In ROMMOM I got some strange I/O Errors on flash device. Finally i performed a format flash: successfully and tftpdnld'ed the IOS back to the device.
On first restart, I got again an excpection (same as before) but now the crashfile (I can submit infos from the crashfile - if needed) was written to flash w/o problems and the router is now up and running....
Is there ANY indicator for a h/w problem ? (I think yes, cause the config was unchanged since july and the router is running non-stop since december or so.)
Will dealer accept an RMA on this issue ?
Is this a (more or less) common problem with 871 ?
Any other out there with this symtom ?
Any indicator in the dump about the cause ? (I have NO experience in analysing cisco dumps)
Best and thanks,
