| |
We've had a report [1] from users booting the 3.2.1 kernel and getting a large number of KERN_ERR messages that look like:
[ 0.020902] Unable to reset IRR for apic: 2, pin :0 [ 0.020970] Unable to reset IRR for apic: 2, pin :1 [ 0.021012] Unable to reset IRR for apic: 2, pin :2 [ 0.021077] Unable to reset IRR for apic: 2, pin :3 [ 0.021138] Unable to reset IRR for apic: 2, pin :4 [ 0.021199] Unable to reset IRR for apic: 2, pin :5 [ 0.021261] Unable to reset IRR for apic: 2, pin :6 [ 0.021323] Unable to reset IRR for apic: 2, pin :7
Digging through git, it seems that error message was added to 3.2 with commit 1e75b31d63. The commit log mentions kdump, but I don't believe the user is doing kexec/kdump of any kind. It seems a normal yum update/reboot and they hit this.
Are there any details the user can gather to help debug this, or has anyone seen this before?
