Dear Maintainer,
* What led up to the situation?
I noticed a flood of messages (1000 per second!) in dmesg (mirrored in /var/log)
after it filled my drive (16GB of logs total, over a couple of weeks).
The message was:
xhci_hcd 0000:03:00.0: WARN: bandwidth overrun event for slot 6 ep 4 on endpoint
or
xhci_hcd 0000:03:00.0: WARN: bandwidth overrun event for slot 11 ep 4 on
endpoint
(it reoccurred after rebooting, but does not seem predictable).
* What exactly did you do (or not do) that was effective (or
ineffective)?
I unplugged my USB soundcard from my USB hub, and the message flood stopped.
When plugging in the USB soundcard, dmesg reports similar to:
usb 1-12.1.3: new full-speed USB device number 12 using xhci_hcd
usb 1-12.1.3: New USB device found, idVendor=0582, idProduct=0074, bcdDevice=
1.07
usb 1-12.1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-12.1.3: Product: EDIROL UA-25
usb 1-12.1.3: Manufacturer: Roland
* What outcome did you expect instead?
I expect potentially rapidly repeated kernel messages to be rate-limited to a
sensible amount.
I tried:
cd linux-6.1.25/drivers/usb/host
sed -i "s/xhci_warn/xhci_warn_ratelimited/g" xhci-ring.c
sed -i "s/xhci_warn_ratelimited_ratelimited/xhci_warn_ratelimited/g" xhci-ring.c
and rebuilt the kernel.
I have not yet rebooted to test if it fixes my problem.
Thanks for your work on this package,
Claude
