From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Thu, 7 Jan 1999 12:55:22 -0600 (CST) From: Troy Benjegerdes To: linuxppc-dev@lists.linuxppc.org Subject: Linux-2.2.0-pre5 SMP broken on PReP? Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: After working with 2.1.132 for awhile, I decided it was time to try Linus's 2.2.0-pre5, however I haven't been able to successfully boot with it. I have tweaked code and tried various revisions includeing pre1 and pre4 (pre1 wouldn't compile). I have been getting crashes in the ncr53c8xx driver, but the dump doesn't seem to be providing valid information. I tracked NIP in the following dump to ' lmw r29,20(r1)'. From my point of view, it looks like the stack got messed up somewhere. I am also building this kernel in a CONFIG_SMP=y configuration since I am going to work on MTX SMP once the kernel runs again ;). ncr53c8xx: at PCI bus 0, device 12, function 0 ncr53c8xx: reallocating base (Wacky IBM)ncr53c8xx: reallocating base2 (Wacky IBM)< ncr53c875-0: rev=0x04, base=0x1fffe00, io_port=0xffffe00, irq=14 ncr53c875-0: NCR clock is 26691KHz, 26772KHz ncr53c875-0: ID 7, Fast-20, Parity Checking ncr53c875-0: on-chip RAM at 0x1ffe000 ncr53c875-0: restart (scsi reset). ncr53c875-0: Downloading SCSI SCRIPTS. scsi0 : ncr53c8xx - revision 3.1d scsi : 1 host.
