When running Fedora on a Dell 2950 w/ integrated LSI Perc5i
(megaraid), the
system will not boot after upgrading to 2.6.22. The boot message
indicates the
system is somehow seeing through RAID, cannot access logical volume.
This

Hello Sreenivas,
We have already been alerted (by OEMs among others) that the modinfo
on
megaswr driver needlessly shows GPL as the license. Ours is a
binary
only proprietary driver. I have since corrected the MODULE_LICENSE
label
to LSI Proprietary and updated the OEM versions. If
Hello Fred,
There's a LSI 1068 chip that can be found on NEC hardware (also
Intel/Supermicro/Hitachi, ...) and that can provide RAID 0 and 1 based
on a MegaRAID BIOS.
Hmm, no. This is not MegaRAID BIOS.
- LSI1068 'MegaRAID':
pciid 1000:0055
embedded MegaRAID BIOS, providing RAID 0
This patch reduces stack usage in megasas_probe_one() from to 2200 to
156. A patched version of gcc 3.4.3 with -fno-unit-at-a-time disabled
was used on i386 platform.

Rayan,
Thanks. I will be submitting shortly a consolidated patch that includes

With the 2.6.7 kernel there used to be information in /proc/megaraid.
I do not see the same information using the 2.6.11.2 kernel.
Is there anything in /proc using the 2.6.11.2 kernel setup ?
If not there, then anywhere else ?
It is not so much that you had /proc/megaraid in 2.6.7. There are

that step I don't understand... why is it a global *VARIABLE* if it's

I see your point! Are you saying I should use if(sizeof(dma_addr_t)==8)
instead of the shortcut

Arjan, I didn't want to needlessly couple megaraid and megaraid_sas.
Since they are in the same

the fact that this is a global variable worries me.
Matt also has the same concern. I am pasting my response from my reply
to his comment:
I will make this an instance parameter if the idea to reduce as many
global variables as possible.
Hello All,
We are announcing a driver for LSI Logic's new SAS based MegaRAID
controllers. I am submitting the inlined patch in three parts. Please

Please try:
In mbox_post_sync_cmd_fast(...) replace
for (i = 0; i 0xF; i++) {
if (mbox-numstatus != 0xFF) break;
}
with
for (i = 0; i 0xF; i++) {
if (mbox-numstatus != 0xFF) break;
rmb();
}
Additionally, increase the loop counter to a bigger value.
Thanks,
