3ware I/O error

3ware I/O error

[Yves-Gaël Chény]

Hi,
i have had a lot of I/O error (the kernel switch the block device in 
readonly mode), with a RAID 1 on a 3ware 8006-2LP using the 3wxxx for 
8xxx ATA RAID module.
After a lot of test (iozone and over), I have no problem at all with a 
standard 2.6.18 non xen, and with a 2.6.18 xen 3.1 (and with newer linux 
kernel like a 2.6.23 non-xen).

Is-there any change in the 3.2 who can cause this error ?

Regards
Yves

Did you try updating your 3ware firmware?  This solved issues with some of 
my 9550sx cards which only had issues with the Xen kernel.

Odd Xen Kernel module interaction

[Alvin Starr]

I have a network kernel module that I am trying to debug.

It is trying to query the file information for a socket that a userland 
progrm has opened.
So it is accessing current->files and getting back 0x0(null).

This seems to work on a non xen kernel.

It has been quite a while since I have done any kernel hacking so I 
would not be supprised if I am missing something obvious.

I believe the module is compiling correctly. It loads correctly and at 
least some of the information pointed to by current-> is correct.

The calling application has got a bunch of file handles open so there 
should be something in current->files.

Any help,pointers or even "you idiot look here" would be greatly 
appreciated.
