Isn't this already fixed in the latest kernels? At least that is what I heard.

RHEL 4.5 PE2950 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) # modinfo bnx2 filename: /lib/modules/2.6.9-55.ELsmp/kernel/drivers/net/bnx2.ko author: Michael Chan <[email protected]> description: Broadcom NetXtreme II BCM5706/5708 Driver license: GPL version: 1.4.43-rh 49524544DE69B4B5647379F parm: disable_msi:Disable Message Signaled Interrupt (MSI) vermagic: 2.6.9-55.ELsmp SMP 686 REGPARM 4KSTACKS gcc-3.4 depends: alias: pci:v000014E4d0000164Asv0000103Csd00003101bc*sc*i* alias: pci:v000014E4d0000164Asv0000103Csd00003106bc*sc*i* alias: pci:v000014E4d0000164Asv*sd*bc*sc*i* alias: pci:v000014E4d0000164Csv*sd*bc*sc*i* alias: pci:v000014E4d000016AAsv0000103Csd00003102bc*sc*i* alias: pci:v000014E4d000016AAsv*sd*bc*sc*i* alias: pci:v000014E4d000016ACsv*sd*bc*sc*i* With options bnx2 disable_msi=1 in modprobe.conf then # modprobe -r bnx2; modprobe bnx2 I get the following error and the NIC will not ifup - kernel: bnx2: eth1: Cannot allocate firmware buffer for uncompression. I took the msi option out of modprobe.conf but the NIC would still not ifup, even restarting the network service did not get the NIC back online. I ended up leaving the option out of modprobe.conf and rebooting the server for this to work ! I hope to set the disable_msi option on a clients server to overcome a problem they are having, but I need to know why this error occurred on my test box first. Any help appreciated, Cheers Nick . __________ Information from ESET NOD32 Antivirus, version of virus signature database 5163 (20100601) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
