| |
This is the message i get when trying to backup to a tape device. This backup procedure normally works fine, it just did this on a once off. The kernel is 2.6.8.1. Could this be related to a tape running out of capacity but not giving a nice error message?

ksymoops output:
Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
