Hi Bartolomeij, hi Marcelo! Two months ago, I had problems with a >137GB drive on a promise controller. These where fixed by a few patches, and the computer runs fine since then with a patched 2.4.22 kernel. Unfortunately, as far as I can see, none of the patches got applied to 2.4.23-pre7. I know that Alan had a few objections against the patches, and they should be addressed, but as things are now, plain 2.4.23-pre7 would lead to severe data corruption if I used it on my computer. For reference, here is the complete mail where Bartolomeij asked Marcelo to apply the patches: On Wed, Aug 27, 2003 at 12:54:27AM +0200, Bartlomiej Zolnierkiewicz wrote: > Marcelo can you apply these patches? > > On Wednesday 27 of August 2003 00:31, Jan Niehusmann wrote: > > Hi! > > > > Two weeks ago, I tried two patches against 2.4.21 regarding LBA48 > > support.

Consult the archives for details, it's all been on linux-kernel. Even though I could easily fix 2.4.23 for myself, I'd really like to have the official kernel work without local patches. And I guess an increasing number of people is using drives >137GB, so it can easily hit other people as well. Jan
