This is what happens when you don't upstream your local changes. And no, saying "But we're a small company and nobody cares" isn't an excuse - Linux carried the entire Voyager architecture around for several years for 2 machines. Not two models, 2 physical machines, the last 2 operational systems of the product line. (Not the Xubuntu-based Voyage distribution either - the Voyager was a mid-80s SMP fault-tolerant system from NCR with up to 32 486/586 cores and 4G of memory, which was a honking big system for the day...) https://kernel.googlesource.com/pub/scm/linux/kernel/git/rzhang/linux/+/v2.6.20-rc1/Documentation/voyager.txt The architecture was finally dropped in 2009 when enough hardware failures had happened that James Bottomley was unable to create a bootable system from the parts from both... So if your production run is several thousand systems, that's *plenty* big enough for patches and drivers (especially since drivers for hardware you included in your several-thousand system run are also likely applicable to a half dozen other vendors who made several thousand systems using the same chipset.... --==_Exmh_1560961607_1605P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBXQpiRgdmEQWDXROgAQLgiQ//UFBElVIVrz2j6hgbDsxrSxbNiWZ78XOp zPJi/jWSZmMEt4QpNByA1Ll6udI5h7c3MprYyiFm3YCToErjrV24+LgkCNqGzV3g 23AY8/bqTjLnA10eT87df7SOdHkfw5CKH89LCEeq1RqK7UYIAN2CMT0MRaPQriD2 NwoJipNt5YamEDZcZEiVqLWtw2mmLTLEt+kZRg57m9scTrSF96Rg10VFzvA9yi2J 4RUBNmnGNTh/2qXjkIWa126v/jaYrcktuoaMYgUuVQnvZxb8K8VzkawE0yvyVhsV Xn0B3WpNmg61Z9C23hmjSTw/XCn9a0vVXckDeoWYEI1fQgT1okgMQegHvtcUAniN Bilmu9+FxVCdus0s4SnjH2jE7dIUXj328ys4imgMidBXxsSMpA6Iht+50/vgxKLV XOkdffMF7aw3IWiLvsKagEybyq/1VYGnbmAU+h4GrJphs5Qs55J1CDLTGDcrUKqj QSlr48Bs4fGgqiPYs9G5U7e1KXRJdcn8zhmx2HxvDudAqnXVKonxj9cvFqdxHs83 wWB4Bvp+DCksNVefEXpSXbZddKqmiU51F2lH8WMZ5dxhA/WN+r/oiMRh28gzS0yR 0xVbWJWDnca0Mn+hp0RioICxIljGiEvQTiWK9IrDj8zJpQNPCntCuqmYQ82bj8yB 8YAja57nMkE= =641k -----END PGP SIGNATURE----- --==_Exmh_1560961607_1605P--
