Did someone see the same issue? My machine has a qla fiber card.
This error is triggered because parameter buf of qla2x00_read_nvram_data
is 0.

Sorry for missing kernel info. I used kernel 2.6.23-rc2. My machine is
a x86_64, but I installed i386 os on it.
If I disable CONFIG_SCSI_QLOGIC_1280 and CONFIG_SCSI_QLA_FC in kernel config,
kernel could boot.

Hi,
what version of kernel do you use?
I read the code, maybe 23-rc1-mm2 fixed the bug.
-mm2 add the code to alloc nvram buffer.
