Re: [SCSI] Driver broken in 2.6.x?

Hi,

As told, I tested it w/o nvidia module loaded, here's what I found:
1. It now doesn't hang on scanning for devices.
2. It now hangs on acquiring preview, logs will follow.
2a.Not it hanged on scanning for devices again, don't know why.
3. It's true for both module loaded and w/o it.
4. xsane badly reports my scanner as Plustek 12000 or such.
5. Turning on "partial updates"(or such) in view->updates, coused whole
machine to hang up, hard reset was needed. W/o this, only xsane hanged.
Shoudln't kernel protect form that somehow?
6. Anytime xsane fails/hangs, it hangs the scanner, making it blink it's
lamp all the time, and it needt to be dissconnected form electricity to
work.
7. As a side question: any way to "reload" the whole SCSI subsystem, so
I don't hjave to reboot if I connect something new?
