Kernel width "HIGMEM64G=y" kills my adaptec hw-raid
Hi!
I think I found a bug in kernel-source-2.6.8-16sarge4. I'm trying to
compile it width HIGHMEM64G support as I have 12Gbyte RAM. To compile it I
run:
# make-kpkg clean
# time fakeroot make-kpkg --initrd --append-to-version=kk2 kernel_image
kernel_headers modules_image kernel_source
I install it width dpkg and everything looks fine.
I restart and finds my new kernel in Grub-bootloader
When it get's to the line below it stops:
EXT3-fs: mounted filesystem with ordered data mode.
I wait a minute two and then both my 36Gb scsi-disks starts to indicate
DISK FAILURE. I also get som SCSI-bus reset error. I have a adaptec
raid-controller with a raid-1 setup for the two disks. To get the server
going again I have to unconfigure both disks in the
"adaptec-bios-raid-configuration-tool" and then reconfigure everything and
build a new raid.
The only thing I add to the kernel is the HIGHMEM64G support using "make
menuconfig" If I compile the kernel adding nothing everthing works fine
except for the last 8Gbyte RAM that I'm unable to use.
Here's a diff between the to kernel configs.
m0002:/usr/src/kernel-source-2.6.8# diff .config_working .config

Am I doing something wrong or have I found a bug?
