Hi, Running RH 8 distro with upgraded 2.4.19 kernel on a Dell Inspiron 7500 (PIII).
I have an Epson GT-8500 scsi scanner attached to the laptop with an Adaptec 1460A SlimScsi PC card adpater. I use the aha152x kernel module as a driver. This combo used to work perfectly (no problems with detection or hi resolution color scanning) until my recent upgrades of kernel and RH version. Now with anything more demanding than binary mode black and white scans, SANE quits and, if I remove the card, the whole system freezes because Linux gets into a loop trying to reset the bus and I have to reboot. I'm wondering if this is a buffer size problem. Any insights would be most gratefully accepted. Here is the output of /var/log/messages: Jan 7 15:17:59 localhost cardmgr[455]: socket 0: Adaptec APA-1460 SlimSCSI Jan 7 15:17:59 localhost cardmgr[455]: executing: 'modprobe aha152x_cs' Jan 7 15:18:01 localhost kernel: aha152x: processing commandline: ok Jan 7 15:18:01 localhost kernel: aha152x: BIOS test: passed, detected 1 controller(s) Jan 7 15:18:01 localhost kernel: aha152x: resetting bus...
