Hi,

following system: Dell PE2650, 2 2.4ghz Xeon, 1gb ram, Dell Perc4DC Controller

It has EL5 installed, but I wanted to change to Centos because of the missing workstation packages in the entry server repository.

The system was redhat up2date until yesterday, so the latest kernel was missing. I changed redhat-release to centos-release packages and the new centos kernel was installed the via yum.

This kernel does not boot.

Error messages: i20:iop0: Get status timeout i20:iop0: Reset timeout i20:iop0: could not reset controller i20:iop0: Reset timeout kernel panic

Here are my findings when setting emulation in scsi adapter bios to i2o:

• initial redhat el5 install fails, no adapter found (mayby centos

install is affected, too, have to set to 'mass storage' to install)

• redhat's kernel-2.6.18-8.1.1.el5 and kernel-2.6.18-8.1.3.el5 boot with

i20 enabled

• centos latest 2.6.18-8.1.3.el5 does not! error messages above
• setting to 'mass storage' all is fine

Is this really a centos kernel problem (I read in centos kernel changelog about special centos changes), or is this for any reason because this is actually a redhat system?

We built the kernel as they released it ... the only change SHOULD be the way the kernel modules are signed.

Thanks, Johnny Hughes
