I am not on on the kernel mailing list please CC to me
I upgrade my computer's ram from 512MB to 2GB of ram and complied in
high mem support 4GB.
My system uses the XFS filesystem as my root filesystem. my distro is
debian sid. my system is an athlon 700 mhz slota on an abit KA7 (KX133
based chipset) my system is all scsi. my scsi card is an adaptec 2940UW(
I also have an 2940U2W I can switch it with). I have two hard drives
both IBM an 18 gig(DNES-318350W) and a 4 gig(DDRS-34560W). I have a zip
100 scsi and a plextor 12/10/32S.
When I upgraded to 2gigs of ram I was using 2.4.10 then used 2.4.14 and
2.4.16 each did a kernel panic. however none do it with highmem off.
just like others it only happens when copying from dev mounted as /.
however me with I have a second hard drive and a zipdrive that both have
partitions that can be mounted as vfat. the first hard drive also has a
partition that I mount as vfat. it doesn't matter where I copy to the
first hard drive the second hard or the zipdrive I still get the same
I've also had the error locking at making tag count 64( somebody in the
archives said that it doing that is normal. I've had that problem for
years it doesn't hurt anything so I ignore it. so why does it do that?)
I've read through the archives somebody posted the if they change the
#define NSEG from 128 to 512 it goes away. it went away for me too when
I did that and recomplied the kernel it went away for me too.
I found this in aic7xxx_osm.h suggesting the 128 setting was only for
* Number of SG segments we require. So long as the S/G segments for
* a particular transaction are allocated in a physically contiguous
* manner and are allocated below 4GB, the number of S/G segments is
applied the debug patch with NSEG set to 128 (default) on kernel 2.4.16
here are my results:
too few segs for dma mapping. Increase AHC_NSEG
