Re: 2.4.26rc1 / HPT 374 / RAID = data read corruption with disks onprimary channels.

Dear Tomi, all,

This patch appears to have cured the problems I was having.  5 loops
over a 2GB file have shown no errors in copying or differing checksums.

The only difference in testing is that I am logged in remotely, rather
than from X on the server itself, though it will be a few more hours
before I am in front of the machine again.

Thanks for the patch Andre/Tomi.  It has seemingly cured the silent disk
corruption I was seeing.

Marcelo - I'd certainly recommend this patch for 2.4.*.  2.4.26rc1 was
giving random 4-byte corruptions for me without it.
