Proliant hangs with 2.4 but works with 2.2.

Proliant hangs with 2.4 but works with 2.2.

[lafanga lafanga]

I have a Compaq Proliant 1600 server which can be hung on demand with all 
the 2.4 series kernels I have tried (2.4, 2.4.1 & 2.4.2-pre3). Kernel 2.2.16 
runs perfectly (from a default RH7.0).

I have ensured that the server meets the necessary requirements for the 2.4 
kernels (modutils etc) and I have tried kgcc and various gcc versions. When 
compiling I have tried default configs and also minimalist configs (with 
only cpqarray and tlan). I have also ensured that I have the latest current 
SmartStart CD (4.9) and have setup the firmware for installing Linux.

The programs 'gpm', 'kudzu' and 'startx' all hang the server immediately 
after they exit (with exit status 0). I cannot pinpoint why the kernel hangs 
and would appreciate any help. The only thing I suspect it may be is that it 
is a dual processor mobo with only one processor but I don't know how this 
detection has changed in the 2.4 kernels.

Thanks.

Ayub.

I bet you it has to do with the PS/2 port. Do you have a mouse plugged
in?

Does the 1600 use a Serverworks chipset?

[lafanga lafanga]

There is indeed a PS/2 mouse and it is plugged in. As far as I know its an 
Intel 440BX chipset since its a 100Mhz bus.

If you cat /proc/ioports does cpqarray show any registered ioports? I 
think it has a bug that means it doesn't request_region() for the 
ioports it uses and this means that any other driver that tries to 
auto-detect hardware by probing ports can stomp on its toes. This is 
certainly the case for EISA cpqarray controllers which is where I 
found this. I sent a report into arrays@compaq.com or whatever the 
address listed in the maintainers file is but haven't heard anything. 
This bug _may_ only exist for EISA controllers - I couldn't test the 
PCI version since the only machine I have with one in is running that 
other o/s.

The three of them all touch the mouse. Does 

dd if=/dev/psaux of=/dev/null count=256

also hang the box ?

Re: Proliant hangs with 2.4 but works with 2.2.

[lafanga lafanga]

Alan,

You were spot on. Indeed touching the device file causes it to hang. Should 
I recompile the kernel in a particular way to avoid this?

Many Thanks.

I'd be interested to know if 2.2.19pre works or not. I'd like to fix the hang
most definitely.

As a short term cure

rm /dev/psaux

you can use mknod to put it back if you ever need to. But that will disable
PS/2 mouse support on that box somewhat

Re: Proliant hangs with 2.4 but works with 2.2.

[lafanga lafanga]

Alan,

I'll be happy to test out 2.2.19pre. I'm having a little difficulty locating 
it though on kernel.org. Can you or somebody send me a URL for this.

Thanks.

ftp://ftp.kernel.org/pub/linux/kernel/people/alan/...

each 2.2.19pre patch is versus the 2.2.18 base

ie

	tar xvfz linux-2.2.18.tar.gz
	cd linux
	patch -p1 <../patch-2.2.19prefoo

Re: Proliant hangs with 2.4 but works with 2.2.

[lafanga lafanga]

Alan,

I have tried kernel version 2.2.19pre13 and it works with no problems 
whatsoever.

Thanks.

I had similar problem with 2.4.5 Kernel. I managed to solve the problem by 
configuring a working verion of kernel with
NCR53C8XX SCSI support as well as SYM53C8XX. As far as I understood
SYM53C8xx support covers 53C8xx chips better than NCR53C8xx and that makes 
all the difference. Anyone understands why?

[Mr. James W. Laferriere]

	Hello Arturus ,  Fyi ,  The SYM2 version of the 53c8xx driver
	(imo) has better support for both the older & newer chips .
	The first 2.4 kernel with the SYM2 included is 2.4.16 (iirc) .

- NCR53C8XX supports all chips except the 53C1010 (33MHz and 66MHz
  PCI) Ultra-160 controllers.

- SYM53C8XX supports chips that implement LOAD/STORE scripts
  instructions. As a result the 53C1010 Ultra-160 controllers are
  supported (+810A,860,875,895,895A,896).

- SYM53C8XX_2 (aka sym-2) supports all chips from earliest 810 rev.1 to
  latest 53C1010-66. Hopefully will replace SYM53C8XX/NCR53C8XX bundle.

(In fact, NCR53C8XX was only useful for 810 and 815 controllers)

For chips that support LOAD/STORE, the SYM53C8XX and SYM53C8XX_2 drivers
care about the chips not mastering themselves over the PCI, as required by
PCI 2.2 specifications.

NCR53C8XX and SYM53C8XX interface with scsi layer using the scsi-obsolete
interface. SYM53C8XX_2 uses the EH interface.

You are encouraged to use SYM53C8XX_2 (aka sym-2, aka SYM53C8XX version
2). The driver is available in latest 2.4 and 2.5 kernels and can also be
used on 2.2 kernel.
