Title: RE: megaraid 1.14e still broken
I've noticed that there is a module that appears to conflict with the megaraid driver.
(I know this seems strange).
I was having trouble getting the megaraid driver to work so...
I winnowed down my kernel to an absolute bare minimum, added the megaraid driver, rebooted.
It worked.
So, I then basically did a binary search of the kernel features I'd disabled.
This is very time consuming, I know. I rebuilt the kernel several times, adding
a few features each time. I never figured out exactly which module was conflicting, if any,
(because after rebuilding the kernel 10 times, it gets really, really old).
But I believe it was the USB filesystem module, which I never reenabled, because
I don't expect to ever use it.

Venkatesh,
megaraid version 1.14e breaks
I rebooted to 2.4.0 and it's older
megaraid v107 works fine
the raid controller was oem'ed
Dell-AMI so there's not an obvious
upgrade I can burn into it from AMI
page because the product isn't listed
there
when the box boots and before lilo
takes over the message is:
PowerEdge Expandable RAID Controller BIOS 1.25
with an option to go into a configuration utility
program
the box is a Dell PowerEdge server 2300/450,
2 CPU, 1G RAM
Venkatesh, I appreciate your adding debugging
info to the driver to capture this, I didn't
write the full register dump
but did capture the first few debugging lines.
megaraid: v1.14e (Release Date: Jan 23, 2001, 17:55)
unable to handle kernel NULL pointer dereference
at virtual addrss 02cc
printing eip: c01e10bc
*pde=
Ooops:
(followed by full register dump that I didn't copy)
Let me know where to go next.

Try this 1.14e version of the driver and i would be glad if you could let me
know the result.
Thanks

flagging strangeness that latest greatest
kernel, 2.4.1 pre 10, shipping with older
megaraid module, but one that works on our
box!
kernel 2.2.13 ships with v1.04, aug '99, WORKS
kernel 2.2.16 didn't ftp down kernel and check
kernel 2.2.18 ships with v1.11, BROKEN
kernel 2.4.1pre10 ships with v1.07b, WORKS

Can i have the driver version number so that i can see whether we have
already fixed that problem?
Also you can send me the dmesg output from working system ( 2.2.13,
2.4.1pre10). This could gave me some additional data points.
Thanks
Venkatesh

can't ...
because the hard drive is never accessed
so the boot messages are never written out
message was an oops, quick recap
2.2.13 works (RH6.1 env)
2.2.16 breaks (RH7 env)
2.2.18 breaks (RH7 env)
2.4.1pre10 works (RH7 env)
I don't know if the bug's in megaraid or
in the RH7 compiler environment, hence my
stressing that component

Hi,
Can you send me the 'dmesg' output of the failing combination. I
would look into the problem ASAP once i get it.
Thanks

don't know if this has been covered/studied
datapoints I've run across re the megaraid
(scsi raid driver, american megatrends)
box: Dell PowerEdge 2300, 2 cpus, 1G RAM
hard drive setup as single drive via raid
controller
RH6.1, compiled 2.2.13, megaraid works!
RH7.0 install/upgrade breaks on megaraid
then, after forcing RH7.0 upgrade by hand
(completely snuffed up with all updates as of jan 23 am ...)
RH7.0 kernel (out of the rpm box 686 smp) breaks on megaraid
RH7.0 2.2.16 kernel source from rpm
compiled using 2.2.13 .config file
and make oldconfig generates kernel that
breaks on megaraid (used RH provided
scripts to compile with kgcc
