Hi,
[1.] One line summary of the problem:
Interphase x531 driver oopses when sonetdiag is run.
[2.] Full description of the problem/report:
suni.o oops when ioctl(4, SONET_GETSTAT) is called
from drivers/atm/suni.c
suni_ioctl(struct atm_dev *dev,unsigned int cmd,void *arg)
...
case SONET_GETSTATZ:
case SONET_GETSTAT:
return fetch_stats(dev,(struct sonet_stats *) arg,
cmd == SONET_GETSTATZ);
When the sonetdiag program from the atm-0.79
[3.] Keywords (i.e., modules, networking, kernel):
modules, atm, networking, sonetdiag
[4.] Kernel version (from /proc/version):
Linux version 2.4.19-pre2-ac2 (root@sansys4) (gcc version 2.95.4 (Debian prerelease)) #1 Tue Mar 5 12:52:36 GMT 2002
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
ksymoops 2.4.3 on i686 2.4.19-pre2-ac2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-pre2-ac2/ (default)
-m /boot/System.map-2.4.19-pre2-ac2 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

[7.6.] SCSI information (from /proc/scsi/scsi)
[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
It seems to work
[X.] Other notes, patches, fixes, workarounds:
straces sonetdiag shows
socket(0x8 /* AF_ATMPVC? */, SOCK_DGRAM, 0) = 4
ioctl(4, SONET_GETSTAT <unfinished ...>
+++ killed by SIGSEGV +++
at this point the oops has occured.
The drivers work ok even after the kernel has oops and general
ATM with Classical IP / ATM seems to be working fine.
I have the same problem with misc other 2.4.recent > 17
kernels on various PC hardware.
