[Bug 368822] [NEW] iwl4965: Microcode SW error detected

[rajamouli2000]

Public bug reported:


I am using ubuntu 9.04 with the  latest backported modules for 9.04
installed. My wireless network controller is Intel Corporation
PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61). I have
got latest microcode from Intel website (v 228.57.2.23). But i still get
the occasional Microcode SW error detected.

Relevant dmesg:
