| |
Hi!
Yesterday our SMP machine crashed. It's running 2.1.103 on a Compaq Proliant 850R with two PPro 200 CPUs and 128Mb RAM. Disc controller is a NCR 875 and it's using the internal Thunderlan ethernet controller. All drivers are compiled into the kernel.
Any ideas what happened? Is this a IRQ deadlock?
Below is the relevant information that we could get.
This was on the console, printed periodically:
wait_on_bh, CPU1: IRQ: 0 [0 0] BH: 1 [1 0] <[c016b8d6]> <[c01660d7]> <[c0166378]> <[c0172cb2]> <[c0155dff]> <[c01561ff]> <[c01287c0]> <[c012883b]>
