Dear sirs, I recently had to install Mandrake 7.0R2 on a file server including a Tekram 395UW SCSI host adapter. I first thought I was lucky since 7.0 included a driver (dc395x_trm) for the board. Unfortunately, the server quickly displayed numerous warning messages ("arbitration lost but reselection wins" and so on) and finally complained about file systems errors. Once I was sure the UW disks attached to the Tekram were not at fault, I investigated the dc395 driver. I finally made my way to the homepage of it's author, Kurt Garloff: http://www.garloff.de/kurt/linux/dc395/ I found out the current version was 1.26 (now it is 1.27) while the version included in Mandrake 7.0R2 was 1.10. Which is very unfortunate as the revisions 1.23 to 1.26 provide essential workarounds for the bugs of this SCSI chip (which occur mainly on loaded SCSI bus, it seems). The latest revision of this driver compiles out of the box on a Mandrake 7.0R2 system, and I am convinced now that all my data loss problems are solved (I did a lot of file copying and removing through the SCSI chain, which was impossible with the 1.10 driver, even with downgraded SCSI bus speeds). Speaking about bus speed, the documentation of this driver states clearly that due to the numerous bugs of the chip, 20 MHz (aka 20 Mb/s narrow, 40 Mb/s wide) is less than stable and it is safier to downgrade to 10 MHz (hit F2 or F6 at boot time for Tekram BIOS settings). So: 1/ if you have such a controller, please upgrade the driver with the one found abive, or you'll hit BIG problems quickly, and keep away from the fastest bus speed, 2/ if you're a Mandrake developper, please pay attention to upgrade the driver you'll include in Mandrake 7.1. Well, that's a very humble contribution that I'm happy to make to Mandrake Linux, the best distribution so far in my opinion!
