I have a farm full of Rackable Systems 1U machines. Recently I've had a
few machines that were crashing on a all-to-frequent basis. Just prior
to crashing the machine would barf these lines into the logs several
thousand times:
Sometimes this appears just before the timeouts:
Mar 5 12:10:29 and-app /kernel: NMI ISA 2c, EISA ff
Mar 5 12:10:29 and-app /kernel: Mar 5 12:10:29 and-app /kernel: NMI ISA 2=
c, EISA ff
Then 1000's of these:
Mar 5 12:10:45 and-app /kernel: fxp0: device timeout
Mar 5 12:10:45 and-app /kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff
Mar 5 12:10:45 and-app /kernel: fxp0: DMA timeout
Mar 5 12:10:45 and-app /kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff
Mar 5 12:10:45 and-app /kernel: fxp0: DMA timeout
Mar 5 12:10:45 and-app /kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff
Mar 5 12:10:45 and-app /kernel: fxp0: DMA timeout
Mar 5 12:10:45 and-app /kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff
I've seen this on machines running 4.4-STABLE from early December and
again this morning on a machine running 4.5-STABLE from yesterday. None
of these machines get large amounts of any sort of traffic.
All the machines in question are identical hardware-wise. They're all
dual PIII/900's, 512Mb RAM on a Tyan Thunder 251x motherboard.=20
dmesg and kernel config included below.
Anyone have any ideas? Let me know if you need more info. I may
also be able to provide a place for someone to take a look on the
machine if need be.
