Hi,
Thanks-- patch applied and booted to the new kernel, so just so everyone
knows, I am running three patches atop of 3.1-rc4:
(for the igb problem/memory allocation issue)
0001-Fix-pointer-dereference-before-call-to-pcie_bus_conf.patch
0002-PCI-Remove-MRRS-modification-from-MPS-setting-code.patch
(for the RCU/memory errors)
0003-filemap.patch
I will try to perform more load tests on the NIC and CPU/MEM/I+O and see
if any of my problems return!
Justin.
Hi,
Been running a lot of stressful jobs and will let them continue, so far,
no ERROR, WARN or OOPS yet.
3.1-rc4 + the three patches above seem to fix the problems (thus far).
Does anyone know when the bugs were introduced into the kernel, as some/all
of these problems also happened with 3.0.x.
Justin.
