First, let me make sure my C is okay, by 'set the host->wish_block
flag in the scsi host structure', you mean removing '#if 0' at line 360
and #endif at line 367 in linux/drivers/scsi/scsi.c? (I was an English
major in college, and only did a bit of pascal programing on an IBM 3090.)
If I was correct in removing those two thingies, and
re-compiling, its still panicking.
Ideas? Should I move this to the SCSI mailing list? Is this
something important? Granted not many people would be foolish enough to
slap two old isa scsi cards into a SMP system, but I grab what I can get.
Another thing, when i do any kind of scsi activity, my network
card stops working. I then need to 'ifconfig eth0 ; /etc/rc.d/rc.inet1' to
get it working again. All my system info was submitted a bit ago.
Thanks for any advice:
