the error indicate fail to read data from EEPROM, your 2nd report is
even more strange, the number at the end the error message indicate the
index of DWORD driver trying to read from EEPROM.
"Time out reading EEPROM[2]" telling me the first 2 DWORD is reading ok
but not the 3rd read.
How many PCI-E slots you have in your system, could it possible for you
to switch to another PCI-E slot, or pull out and re-insert the NIC.
Unfortunately, not. On this laptop, the NIC is not reachable without disassembling the laptop, and I
don't want to... I will double check again, but...
Also, it is possible to put the NIC into different system and see if you
are seeing the similar problem?
No, for the exact same reason.
Not that it still happens with 3.0.0-1 from Debian.

The error is not easy to reproduce, but the fix is perfectly stable. A single unload/reload of
iwlagn is always enough to solve the problem, when it happens. For this reason, it sounds difficult
to consider this a hardware slot problem. Can't this be related to some other PCI components?

I'm quite sure I can fix this problem by loading, unloading and reloading iwlagn on every startup...
but I don't really consider this a fix :-/
