Linux temp 2.0.33 #6 Sat Apr 18 16:26:06 EDT 1998 i686 unknown (some patchs, but standard aic driver that come with it, patchs are only exploit/crash patchs) only way I could get current driver to work, and not time out every second. Was to turn speed down. turn off disconnection, play with some of the other settings. If I had the default settings like 40 or 20mb , disconnections etc..... I couldn't even boot. All cables/terminals where professionally tested(by local cable manufacture) Installed freebsd, worked fine. Think it was said, before on the list, alot of problems are in scsi.c code, These problems have also shown up on other scsi controllers. Try lowering everything down, and turning off the defaults. just to see if it works. I wouldn't be surprised if it started working better. ( I also have my drives as cheap raid drives(md utils) which actually helps a bit, cause not one drive gets overloaded. Only bad part is,once in while i still get time out under really heavy load, and end up losing data) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
