next in thread | raw e-mail | index | archive | help
I've communicated with a few people about this off-list, and it was sug-
gested I give the issue some wider exposure on this list in the hope of
having it addressed for 5.4-RELEASE. It may or not be related to the other
interrupt storm problems some people are seeing.
I have a number of systems running the latest 5-STABLE (as of 4 PM today
or so). I've been seeing this issue for quite some time, though (5.3-RELEASE
at least, though I don't remember it happening in 5.2.1-RELEASE).
The first symptom is that at boot time, I see these messages:
Interrupt storm detected on "irq16: uhci0"; throttling interrupt source
Interrupt storm detected on "irq17: ichsmb0"; throttling interrupt source
Next, during the whole time the system is up, a "systat -v" shows that my
uhci0 and ichsmb0 devices have active interrupt counts (despite no activity
on them) which happen to *exactly* correspond with "real" interrupt activity
on other devices.
The motherboards are Tyan S2721-533's. The rest should be apparent from the
dmesg output.
I'm attaching two consecutive screen captures of the systat -v output as
well as the dmesg output.
This happens on both SMP and UP (with a UP kernel) configs, and also with
or without ACPI enabled (by option at boot time).
Let me know if anyone needs further information to help diagnose this. I
can also provide remote access to a test system if a developer needs it.
