Hello,
I've recently performed an install of i386 OpenBSD 6.4 on a HP T5740
thin client (Atom N280, 2GB DDR3, 2GB FLASH, more info on
parkytowers.me.uk) and I keep running into uvm_fault errors at xenodm
startup when booting. At this point the whole computer freeyes, even
ddb prompt appearing after the error message doesn't work. Single user
boots fine, and doesn't produce any errors whatsoever. I have attached
the single mode dmesg, the disklabel output (I use the install
defaults), and pcidump output with this email.
When booting without any options at boot> prompt, the machine boots
normally until it starts xenodm, at which point the screen flashes
black, as expected at xenodm startup, but then goes back to console,
presenting the following error message:
uvm_fault(0x0d0d55bf0, 0xd2eaf000, 0, 2) -> e
kernel: page fault trap, code=0
Stopped at uvm_pmr_get1page+0x35d: movl %ecx, 0(%edi,%eax,1)
ddb{1}>
When booting bsd.sp kernel, results are very inconclusive. Most often
it results in the same crash as bsd.mp, but in very rare cases it also
crashes at kernel relink time. This didn't want to happen the many
times I have restarted the machine on purpose to trigger the relink, if
anyone can help me force the relink on the bsd.sp kernel, please let me
know. When it reaches the xenodm startup, it fails at the same assembly
line as the bsd.mp kernel.
I have also tested these machines with Alpine Linux, which runs very
stable (I use one of them as my home WiFi access point), so I don't
believe that the machine itself is faulty.
What would be the next step at solving this problem?
