Description of problem:
This is in regards to customer support request #281477.
The e34/e35 family of kernels has a modules.dep problem. After
identifying a temporary workaround to the problem described in bug
#113427, we discovered an anomaly in the 2.4.9-e.34 and e.35 kernels.
The /lib/modules/2.4.9-e.34/modules.dep file has this in it (NOTE:
This is all on the same line):
This tells the system to load a driver that does not function properly
(the 4412k1 versus the 5220k1 driver) when one loads the e1000 driver.
The e.34 and e.35 kernels both have this odd behavior, yet the e.34
that comes in the ISO of update 3 does not! The net result is that if
I install with update 3 over the network (PXE boot), the network card
is found and works but when the system reboots, it is gone even though
the kernel versions are the same! Applying e.35 doesn't help either.
Furthermore, the changelogs between e.34 and e.35 are identical, so I
was unable to determine what all had changed in e.35.
Version-Release number of selected component (if applicable):
kernel-2.4.9-e.34 & 35, kernel-smp-2.4.9-e.34 & 35,
kernel-enterprise-2.4.9-e.34 & 35
Steps to Reproduce:
1. Install via PXE boot / kickstart with a Intel Pro 1000 / MT network
card with RHEL 2.1 update 3.
3. The card that you used to install the OS with is suddenly gone
until you correct the /lib/modules/`uname -r`/modules.dep
I don't see this at all under e.34 or e.35 kernels. I get 3 separate
line for a grep of e1000 in the modules.dep file:
chai / 10# grep e1000 /lib/modules/2.4.9-e.35enterprise/modules.dep|wc -l
chai / 11# grep e1000 /lib/modules/2.4.9-e.35enterprise/modules.dep
I've seen it each and every time. The hardware I'm using are Dell
PowerEdge 2650's with BIOS A17 when an Intel PRO/1000 MT Dual Port
Server Adapter (version on the card: 82546GB, version on the box:
A85400-006) is present. They are done with a fresh kickstart via PXE
boot from update 3 of RHEL v2.1.
Incidentally, our tests indicate that you *must* have the card in
question to get the behavior.
i just installed U3, and e.34 came up fine withe the e1000 driver. i
then ran up2date and rebooted into e.35, which failed to set up
networking b/c the dependency metioned aboved showed up in the
modules.dep file. i re-ran depmod serveral times and the dependency
went away and the module loaded fine. i'm really not sure why depmod
is producing different results.
Workaround to be applied immediately after updating to the 2.4.9-e.35
cp $FILE $FILE.save
sed -e '
' $FILE.save > $FILE
thanks for helping us get to the bottom of this.
The issue will be fixed in the next kernel update, which should be
fairly soon. in the meantime, if you want to test with the release
candidate its e.37 and on my ppl page, however its not an 'officially'
supported kernel yet.
changing to modified state, as this issue should be resolved.
