Randolph made the matching config/System.map available to me.

data page fault. looks like a null ptr dereference.
Above Kernel addresses point to:
0x101e0e7c opost+c8
0x101e27e4 write_chan+1ec
0x101e25f8 write_chan+0
0x101e0bec do_tty_write+134
0x1014b828 path_walk+14
0x101de398 tty_write+30
0x10104a6c handle_interruption+150
0x1013f4ac sys_write+a4
0x10109f90 syscall_exit+0
0x10109084 intr_check_sig+0
0x10109d4c child_return+0
0x1013ff24 chrdev_open+64
0x1013e3e4 dentry_open+f4
0x1014ec28 locate_fd+70
0x101213f0 it_real_fn+0

Seems like a jumble of stack traces.
Start with IOAQ (0x101e0dcc opost+18) and GR02 (rp, 0x101e27e4
write_chan+1ec) and look at source code to see which
kernel stack addresses are valid.

In any case, doesn't look like a problem with tulip driver.
I'll let someone else keep poking at this.

This is bad. The kernel branched off into the weeds
or something. Could be the same problem though.
