dc395 with a scanner, failing.

Hi there... I own a dc395 scsi card "working" on a Debian GNU/Linux 3.0, with kernels 2.4.22 and 2.6.5.

On the 2.4 series kernel it works flawlessly using the old driver from Garloff, but on the 2.6 series (using the new one, included in the kernel source) it seems to work, but while scanning with sane the scanner freezes for some time (minutes) until I cancel the scan and wait for a while until the scsi processes end :-(

I've tried changing the parameters for the kernel module (while loading the module) but no combination seem to solve the problem :-(

The scanner is an old HP ScanJet 3c.

What other tests should I do to send some feedback to the list and try to find a solution? Anyone had this same problem?

Thanks in advance.

So it works fine in 2.6.5 and not 2.6.6? I'll have to look at what other changes went in between those versions.

[...]

Edit the top of drivers/scsi/dc395x.c and uncomment the first "#define DEBUG_MASK" line, rebuild the dc395x module, reload the module and then the operation that failes again. You should then gets lots of debugging output in one of your log file which you can then gzip or bzip2 and then send directly to me and I'll take a look at it.

Thanks.
