Linux kernel 2.6.16 on 7025-F50 with ServeRAID 4H adapter - IPS driver failure
Good day,
cannot find any reference to successful installation of IBM ServeRAID adapter
for RS/6000 machine with Linux. I am not using Debian linux (it is rather Red
Hat FC5-ppc) but I presume kernel/drivers are more or less the same. Managed to
start Debian netinst CD for PPC platform (version 3.1r2, AFAIR) and got same
results with kernel 2.6.8, while 2.4.27 just hangs somewhere in the middle. The
adapter itself shows up (using lspci -v) as:
0001:40:0c.0 RAID bus controller: IBM SCSI RAID Adapter [ServeRAID] (rev 10)
Subsystem: IBM ServeRAID-4H
Flags: medium devsel, IRQ 23
I/O ports at e4000800 [size=256]
Memory at d7f00000 (32-bit, non-prefetchable) [size=1M]
Expansion ROM at d7eb8000 [disabled] [size=32K]
Capabilities: [40] Vital Product Data
Capabilities: [48] Power Management version 2
when starting installed system, IPS driver fails with message:
ips 0001:40:0c.0: unable to read config from controller.
ips 0001:40:0c.0: Unable to initialize controller
ips: probe of 0001:40:0c.0 failed with error -1
manual IPS driver modprobe fails with message :
ips 0001:40:0c.0: Couldn't allocate IO space feffe800 len 256.
ips: probe of 0001:40:0c.0 failed with error -1
, while if I start kernel from the CDROM (install/rescue kernel), driver does
not load with a kernel BUG message.
Anyone managed to run this (or similar adapters) using IPS driver on RS/6000
platform under Linux?

PS. tried same machine with AIX 5.3 - RAID adapter works fine, so hardware seems
to be OK. Machine has 4 x PowerPC 604e 332MHZ CPUs, 3GB RAM, 2 x LSI Logic
53c825 (for CDROM), 1 x LSI Logic 53c1010 (for boot sixpack), three Ethernets
(10 megabit, 100 megabit and a Gigabit one), and, finally, 4-channel ULTRA3 RAID
(IBM option no. 2498) I am talking about.
