machine checks on VAX/780 under 4.1BSD

[reece%nadc at sri-unix.UUCP]

Can someone decipher the following machine check? We get it about
once every two days (machine usually reboots itself). Maybe there
is a write-up on machine checks available somewhere? Here it is:

	machine check 2: cp tbuf par fault
	cpues 10084 upc 1100 va/viba 800147e6 dreg 1efd5 tber 7e01 2100
	timo 1338 parity 4000 sbier 8002 pc 80001338 psl 4150000 sbifs 2000000

Thanks for any help.
