Comment (by waddlesplash):
Gave up after 20-30 attempts, ending the wireless test and going wired
instead to post this. Possibly same "station deauth" symptoms as before:
Can you kill wpa_supplicant and run it in a terminal, and paste the error
messages that it gives here? That's more interesting than the syslog in
this case.
early during the test, I got greeted by a KDL "attempting to clone
kernel area".. It was continuable (!) so ended up logged, luckily: (was
followed by the userland media srv crash that always occurs on this
machine):
Non-page-fault KDLs typically are continuable, yes.
KERN: PANIC: attempting to clone kernel area "dpc: normal
priority_14_kstack" (296)!
Um... Woah. That's the Media Kit attempting to clone a kernel stack area,
which definitely should never occur. It's entirely possible this is the
source of at least some of the weird memory corruption you sometimes see.
I wondered if there were bugs like this that introducing that panic would
uncover, and it seems there are :)
I'm not sure why it tries to clone that ID, but what's stranger is that
should just return B_NOT_ALLOWED, and then
[

BBuffer::BBuffer should exit early] followed by
[
http://xref.plausible.coop/source/xref/haiku/src/kits/media/BufferCache.cpp#45
GetBuffer returning NULL] as Data() should be NULL since the clone failed,
except somehow it isn't...?
