I tried to install 5.1-release and got i running - the error occurred, still. Where 4.8 just hung, 5.1 did manage to give me some more info: the problem is ATA timeouts for my CD. This seemed to be a problem for many ppl out there, and not once I came by aworking answer. At boot time, after probing the HDs, its time for the CD, but it hangs for a while, then following error messages start to appear. They appear anything from 10 to 30 times before the computer boots up. acd0: read data overrun 34/0 acd0: MODE_SENSE_BIG command timeout - resetting ata1: resetting devices... done This problem seemed to come along 4.6RC2, and it's errdata sure has it mentioned. The fixes there did not work on my computer, thou. I have tried to play with sysctl and device.hints, and dis/enabling UDMA support in BIOS, adjusting cables etc., all in vain. The problem seems to be with particular CDROM brands, as one older Toshiba worked fine. Should I make a bug report out of this? It seems like a big problem to many, without any fixes. Is it a bug in the driver? My computer is a MSI6330(KT133) mainboard, 30Gb UDMA100 HD as primary disk in ata0-master, 10 Gb UDMA66 slave in ata0-slave where FreeBSD resides (master has Win98 and FreeBSD boot manager), and HP CD-Writer 8200i CD-RW in ata1-master. When adjusting the device.hints I got FreeBSD to get it as UDMA33, as it should. I don't need the CD in FreeBSD (but it wouldn't hurt to have it either), so the only harm in this is that the booting takes forever. I don't want to disable anything from BIOS, because I use it in Windows, and I don't want to restrict it's use/efficiency. Any thoughts appreciated. --Ville -- Ville Lundberg ville.lundbergATwelho.com http://www.hut.fi/~vlundber
