Description of problem:
I had scsi_hostadapter set to AM53C974 in modules.conf. When I updated to the new kernel in 'updates' it added a new 'alias scsi_hostadapter1 tmscsim'. When I reboot it first loads AM53.. and then tmscsim which makes the system ooops right after tmscsim has been loaded.

When probing for scsi adapter it always gives me tmscsim, but I wanna use AM53C974 instead since it works better for me. Once I removed the extra line and reran mkinitrd it worked fine.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Change scsi_hostadapter
2. Update kernel
3. Verify that you have a new scsi_hostadapter line

Can you reproduce the *exact* steps to get the new entry added to modules.conf?
Does running /usr/sbin/module_upgrade do it?
Comment 2 Per Winkvist 2002-10-21 14:49:17 EDT
I repeated the sequence I did yesterday and this time the new kernel booted fine. Very strange.   
Another thing I observed yesterday was that after I had used the rescue disc and removed the  
extra scsi_hostadapter line and rebooted it didn't actually work right away. So I had to use the  
rescue disk again. The second time I removed the initrd and did mkinitrd again, then rebooted  
A final thing, upon boot I get the following :
