Translation Look-Aside Buffer (TLB) Reload
Causes Errors With Certain Linux Software
(6296473)
Note –
We recommend that RHEL3 users install the most recent OS update on the
server to alleviate this issue. (At the time of printing, the most recent update is
RHEL4 U1.)
The BIOS Advanced menu (CPU Configuration menu), in the BIOS Setup utility,
contains an option named “Speculative TLB Reload.” By default, this setting is
enabled, which allows TLB reload.
With this default setting, you might see errors similar to the following on systems
running any 64-bit version of RHEL or SLES with Service Pack 1.
Northbridge status a60000010005001b
GART error 11
Lost an northbridge error
NB status: unrecoverable
NB error address 0000000037ff07f8
Error uncorrected
Workaround
To avoid these errors, disable TLB reloading:
1. Reboot the server and press F2 to enter the BIOS Setup utility.
2. Go to the Advanced -> CPU Configuration menu.
3. Use the arrow keys to highlight the Speculative TLB Reload option, and change
its setting to Disabled.
This disables TLB reloading.
4. Save your changes and exit the utility.
