Description Pavel Urban 2003-01-21 11:58:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0.2) Gecko/20021216

Description of problem:
While booting kernel made from kernel-source rpm, it hangs after

megaraid: v1.18d (Release Date: Wed Aug  7 18:51:51 EDT 2002)
megaraid: found 0x101e:0x1960:idx 0:bus 5:slot 0:func 0
scsi2 : Found a MegaRAID controller at 0xf88b2000, IRQ: 21
scsi2 : Enabling 64 bit support 

This only happens when megaraid (and whole SCSI support) is compiled as
built-in. When I try it 'redhat way', ie compile it as module and boot via
initrd, everything goes ok.

My hw is:
Dell PowerEdge 6600, 4xXeon/2GHz, 16GB RAM, PERC with 8 disks in RAID 0+1
(mirrored stripe), QLA 2200 for external disk array (not used right now), AIC
7892 (dtto). Kernel is compiled from kernel-source-2.4.18-19.7.x.

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

How reproducible:

Steps to Reproduce:
1.Build kernel on described platform with megaraid and scsi support built-in

dmesg from successful boot

This is /var/log/dmesg from kernel created with scsi supoport and megaraid as
modules; boot via initrd.

Comment 2 Alan Cox 2003-06-08 16:23:04 UTC
No idea. Closing because we don't deal with bugs in customer built kernels and
we don't have any ideas what is up either.
