Alrighty, I thought I'd give you the latest on our efforts along these
lines. We are progressing down the paths you suggested, and wanted to
post a few results before the weekend.
We have used nolock instead of gulm, still on the pool device over the
HBA, and received a crash. Attached are two traces of the crashes. We
edited the code sprinkling printk's throughout to get some output.
Using lock_nolock instead of lock_gulm still crashes, but slightly
differently. See koops-nolock.txt
The tracing printk()'s added to lock_gulm and gfs don't show much, but
the crash is different yet again. See koops-gulm-traced.txt
The tracing messages use -> for enter, <- for leave and ?? for
"This function returns in far too many places to bother."
Later this evening or monday, I will attempt building a local file
system without a pool, then with a pool, to give you some more data.
Thanks,
Micah
