I'll try .18 and .20 and see where that gets me - this is my first time
trying to set up packet writing.
Ok, on 2.6.18, I still get the warning about a recursive lock, but no dump
regarding a null pointer dereference. The command still fails, however,
with pkt_get_last_written_failed. On 2.6.20, I get an error similar to the
one I orignally posted (first the recursive lock warning, seconds later,
null pointer dereference).
Not sure about the recursive lock, but something between .18 and .20
happened such that the packet writing driver didn't fail gracefully.
On a side (offtopic) note, I noticed that ACPI support changed for the
better in very recent kernels - on both .18 and .20, there were severe
and early errors unless I specified acpi=off
I'll see if I can figure out exactly where from 2.6.18 to .20 things went
wrong,
