Is that "232 open("/proc/dasd/devices", O_RDONLY" the last line in the
file? If so, it brings me back to requesting, yet again, what you get when
you do a "cat /proc/dasd/devices" command. If it is not, I'd like to see
the rest of the file. If it's too large to post to the mailing list, please
email it to me.

Subject: Re: SUSE install on a OS/390 LPAR
Here is tonight's try with the trace sysout.
SuSE Instsys linuxlpar:/root # rmmod dasd
SuSE Instsys linuxlpar:/root # insmod dasd dasd=04c0-04c4
Using /lib/modules/2.2.16/block/dasd.o
then strace -f -F -o trace.file dasdfmt -b 4096 -n 04c0
The session is just sitting now...
