Hello,
I am running -CURRENT from June 27, 2000 (started cvsup around 19:05)
on a PII 266 MHz with 32MB RAM and one IDE disk.
Initially, I noticed that while syncing disks during a reboot, the
system would always give up before finishing. To capture the output,
I configured the kernel to use a serial console by setting flags for
the serial port in the hints file (hint.sio.0.flags="0xb0").
Now, instead of just failing to sync the disks, the system panics about
two out of every three reboots.
The kernel config file (MONSTER) is included as an attachment, as well
as the hints file. Below is the panic information and stack trace.
Let me know if you would like any more information (this is my first
crack at running -CURRENT, so I'm new at this).
Regards,
-brian
