Looks like a possible SCSI Scipts error. FENRIS, unlike UNIX FS's will talk to more than one disk or partition concurrently since a volume can have multiple segments strip[ed across several drives. May be exposing some timing condition with the way I am calling breada abd bread.</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial size=2>Jeff</FONT></DIV> <DIV> </DIV> <BLOCKQUOTE style="BORDER-LEFT: #000000 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px; PADDING-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A href="mailto:jmerkey@timpanogas.com" title=jmerkey@timpanogas.com>Jeff Merkey</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A href="mailto:jmerkey@timpanogas.com" title=jmerkey@timpanogas.com>Jeff Merkey</A> ; <A href="mailto:linux-kernel@vger.rutgers.edu" title=linux-kernel@vger.rutgers.edu>linux-kernel@vger.rutgers.edu</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Wednesday, June 09, 1999 4:36 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: Oops in 2.3.X, 2.2.X, and 2.0.3X with FENRIS and NCR53c875 SCSI Driver</DIV> <DIV><BR></DIV> <DIV><FONT face=Arial size=2>More on this -- am also getting "..could not get a free page...". Tracing with a logic analyzer shows memory corruption. Looks like an errant Data Transfer. Machine is a dual processor 500Mhz PIII Server. Problem only shows up when SMP is active.

Not my bug, I will get Oops specific info. Complains that the LRU Block list has been corrupted. Only happens with the NCR driver and the 53c875 Chipset. Could be a scripts bug since the NCR SCSI chip can program it's own DMA from the SCSI scripts.</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial size=2>Jeff</FONT></DIV> <DIV> </DIV></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
