Subject: 2.2.0pre2 SCSI problems, more

Hallo!

  I have been having troubles with SCSI on all kernels after 2.1.130.
Actually, the 2.1.130 I'm using is prebuilt so that may have something to do
with it. 2.1.127 (built by myself) worked fine. Here is an excerpt from my
boot log for 2.2.0pre2:

scsi0: MESH
scsi1: 53c94
scsi: 2 hosts
mesh: target 0 aborted        <-- ??? this is my problem...
mesh: target 2 synchronous at 5 MB/s
Vendor: QUANTUM Model: FIREBALL SE2.1s
[followed by normal scsi information on the rest of my busses]

  Booting from 2.1.130, the /proc/scsi/scsi entry for the device skipped
above is:

Host: scsi0 Channel: 00 Id: 00 Lun: 00
   Vendor: QUANTUM Model: FIREBALL1280S Rev: 630G
   Type: Direct-Access

  On the boot previous to that one, it seemed to go fine, until the
following:

Machine check in kernel mode.
Caused by (from msr) : regs cba7dbf0 Machine check signam - probably due to
mm fault with mmu off
NIP: D0832290 XER: E000BE6F CR: D0832238 REGS: cba7dbf0 TRAP: 0200
NSR: 00001030 TASK: cba7c000 [76] 'insmod' mm -> pgd cbc9000

  that's copied down from a stickie, so maybe a number or formatting is wrong
somewhere... So are the boot messages for SCSI stuff above, for that matter.
  Normally (I only got that Machine check thing once) it drops me to single
user mode, and gives me a prompt. Mount lists /dev/sdb5 mounted at / (which
is as it should be, except that it had told me earlier that my ZIP drive had
become sdb since my first drive wasn't detected).

I am using debian-powerpc potato, libc6 2.0.100... Please tell me if there
is any more information I can give you.

Thanks,

Peter

paul,

i removed all devices from the second bus except for an 80M quantum drive
that i used to boot from.  (everyone should be warned that you should boot
from a non-mesh device when mesh debugging is on! :) 

a strange thing, and maybe bad news for debugging: the drive is discovered
properly by the debugging kernel. maybe it's a timing issue. i hope the
logs can tell you something. 

the problem drive is on scsi id 1.
