Driver Update Model Updates Kernel Entries On GRUB Boot Selection Screen

Description When using Red Hat Enterprise Linux 5 driver update model or dkms to update kernel modules,

multiple Grand Unified Bootloader (GRUB) entries appear at the kernel selection screen on

system boot.

Workaround Driver update model creates modified initrd images when it updates a driver required for

system boot. This behavior is expected and the default boot kernel contains the most recent

applied driver changes. For more information, see the Red Hat Enterprise Linux 5 Release

Notes at redhat.com.

USB Devices Are Reset During Stress Test

Description When a stress test is run on some Dell PowerEdge systems, the following message may be

displayed:

usb 3-3.1: reset low speed USB device using ehci_hcd

and address 7

Cause This occurs when low or full speed devices are connected through a USB 2.0 hub to the

Enhanced Host Controller Interface (EHCI) hub and PowerNow! is enabled. The EHCI starts

split transactions, but gets delayed while trying to access the main memory. Therefore, EHCI

cannot complete the split transaction before the transaction translator (TT) in the hub discards

the data. The hid-core driver retries these transactions, but if the retries also fail for one

second, the device is reset.

This is a known issue.
