iSCSI Login To Dell EqualLogic Storage Array Over IPv6 Might Fail

Description iSCSI initiator login to the IPv6 address of an EqualLogic iSCSI SAN array may fail.

Workaround This issue does not affect iSCSI session login to the EqualLogic Array’s IPv4 addresses.

Cause This issue occurs when an error in iscsi-initiator cannot handle IPv6 TargetAddress and

redirects from the EqualLogic array.

CPU Soft Lockup On Red Hat Enterprise Linux 5 Update 3 Xen Kernel

Description On systems running Red Hat Enterprise Linux 5 Update 3 xen kernel, network traffic through

Broadcom BCM5709c may cause a CPU soft lockup along with call traces. The system may

become non-responsive.

Workaround Load the bnx2 driver with the module parameter disable_msi=1 using the command:

modprobe bnx2 disable_msi=1.

USB Resets On AMD System

Description During I/O operation, the following message is displayed: usb 3-3.1: reset low

speed USB device using ehci_hcd and address.

Cause This issue 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 experiences a delay while trying to access the main

memory. Thus, 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 fail for a second, the device is

reset.

Bonding Driver Cannot Be Successfully Unloaded

Description If you unload the bonding driver using rmmod bonding, the unloading may fail displaying the

following error message: unregister_netdevice: waiting for bond0 to

become free. Usage count = 1.

Workaround Blacklist the IPv6 module if IPv6 addresses are not used.

NOTE: To blacklist the IPv6 module, save install ipv6 /bin/true in a file under the

directory /etc/modprobe.d/.

Cause The unloading fails because of reference count leak in the module exit path.
