Hi all,
I am having a repeatable panic in the nfs server code.
I have a -g compile kernel and a vmcore file.
dmesg output included
Should this be sent via send-pr?
Anyone else seeing this sort of nfs bug?
Another problem that this system has:
The Promise card has the prom removed, cause the system will not
recognize the disks connected to it when the prom is in there.
I believe that this results in the disk access timing being off
so that transfers are about half of what they could be.
The MBoard is a Matsonic MS6260S running at system clock of 100MHz.
The CPU is rated for more than 300 MHz. i.e. the system
is not overclocked.
The gdb-aout's where command produces:
