Description of problem:
Kernel panic on boot of RHEL5 with chelsio T3 dual port 10G adapter in the machine.
Version-Release number of selected component (if applicable):
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.2 (Tikanga)
# uname -a
Linux netpc??.lab.?????.com 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
0a:00.0 Ethernet controller: Chelsio Communications Inc T320 10GbE Dual Port Protocol Engine Ethernet Adapter
Subsystem: Chelsio Communications Inc Unknown device 0001
# lspci -n
0a:00.0 0200: 1425:0031
Good version of driver pulled from the chelsio web site
# ethtool -i eth2
firmware-version: T 7.1.0 TP 1.1.0
Steps to Reproduce:
1. Install chelsio dual port 10G adapter in a system (T320)
2. Install RHEL5
3. kernel panic at boot
Top of kernal panic stack is at t3_prep_adapter()
Driver downloaded from chelsio web site fixed the problem. The driver in RHEL5
should be updated.
Do you have a stack trace?
Does this still occur on the 5.3 (2.6.18-128.el5) kernel? The driver has had significant updates since 5.2
Apparently this patch will fix it:

cxgb3 - eeprom read fixes
Protect against invalid phy entries in the eeprom.
Extend eeprom access timeout.
This change is already in 5.3, so I suspect 5.3 will work find for them.
ping, any updates on 5.3 testing?
No response, assuming 5.3 fixed it
