[Bug 1291113] Re: Intel igb driver infinite loop in ksoftirqd, uses 100% of cpu 0
Andrew, have you tested the 3.2.0-61 kernel from the proposed channel?
These types of bugfix releases can often be helped along with test
result comments of the form: "I tried the proposed package and it
resolves this problem for me. Hope it is published soon." (or not if it
doesn't, which is the most important thing to know if a proposed bugfix
package does not fix the bug!)
