User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)

Description of problem:
The system fails to boot giving a kernel panic message when trying to boot 
with the 2.4.9-12 kernel.  The 2.4.3-12 kernel boots fine.  The system 
uses a SuperMicro 370DLE motherboard (using 1 processor) and Promise 
Ultra100 Tx2 IDE controller.  The panic message occurs when trying to 
mount the root filesystem.

Version-Release number of selected component (if applicable): 2.4.9-12


How reproducible:
Always

Steps to Reproduce:
1. Reboot the machine using the latest RedHat provided kernel
2.
3.
	

Actual Results:  System hangs

Expected Results:  System should boot

Would you mind giving the panic message ? Without the text there's nothing I can
work with...

Comment 2 jra 2001-11-12 19:24:06 UTC

Here are the last lines that appear on the console before the system hangs:

ide-floppy driver 0.97.sv
request_module [ide-cd]: Root fs not mounted
hda: driver not present
VFS: Cannot open root device "306" or 03:06
Please append a correct "root=" boot option
kernel panic: VFS: Unable to mount root fs on 03:06

Comment 3 Arjan van de Ven 2001-11-12 19:30:46 UTC

I know things scroll by fast, but is there ANY indication that earlier messages
show anything about promise controllers ?

The message indicates that the root device isn't found, /dev/hda in specific

Comment 4 jra 2001-11-12 20:38:54 UTC

There are no earlier messages about the Promise controller.  There is nothing 
in the messages file either.  Unfortunately I have to reboot the machine 
immediately with the older kernel as this is our Web server.

With the 2.4.3-12 stock kernel, there is no problem whatsoever and we have no 
additional boot options added to the original lilo.conf file except the 
word "linear".

Comment 5 Arjan van de Ven 2001-11-12 20:41:05 UTC

Ok one last question
if you type "linux ro root=/dev/hde6"
does that work ?
(no need to look at anything, should work immedatly or not at all)

Comment 6 jra 2001-11-12 20:53:06 UTC

Same results with system hanging at same point.

Comment 7 jra 2001-11-22 19:00:44 UTC

The solution is to recompile the kernel with the option "Boot off-board 
chipsets first support" to Yes.  The stock 2.4.9-12 kernel supplied by RedHat 
will not boot with the SuperMicro 370DLE, Promise Ultra100 TX2 combination.
