Hi,
Upgraded from kernel 2.4.26 to 2.4.31 and got problems with SATA SIL
controller.
This is the patch that fixes the problem (kernel VM access violation,
ksymoops output and this patch also attached):

=========================================================================
I don't understand too much about the mechanics of this driver, but it
seems that symmetry is violated by sequence R0,W0,R1,W2
After replacing it with R0,W0,R1,W1 I got the driver working so far.
This is my lspci for the card:
00:0b.0 RAID bus controller: CMD Technology Inc Silicon Image SiI 3112
SATARaid Controller (rev 01)
Thank you,

ksymoops 2.4.4 on i686 2.4.31smp. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.31smp/ (default)
-m /boot/System.map-2.4.31smp (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
