Description amsibamsi 2010-11-09 12:50:05 UTC 
The USB chip included in CS5536 needs hw.usb.ehci.lostintrbug set to 1
in sysctl. Otherwise it will run into timeouts e.g. on disk I/O and abort
with failed I/O operations. The corresponding conversation is on the FreeBSD
USB mailing list:

http://lists.freebsd.org/pipermail/freebsd-usb/2010-October/009367.html

Fix: 

The sysctl setting should be set automatically. The bug and the connection
to the sysctl workaround is not easy to find. Maybe someone knows how to
add a quirk to sys/dev/usb/controller/ehci_pci.c. With my limited knowledge
of the code I could not figure out how to properly patch the code.

Thanks.
How-To-Repeat: Connect a USB disk, read the whole disk with dd.

Sorry this PR was left unattended. Is this bug still valid? Do you have hardware to verify the fix?

Please try to reproduce this issue with the latest -stable FreeBSD code.

Thank you!

Sorry, don't have the hardware anymore.
Comment 6 Oleksandr Tymoshenko freebsd_committer freebsd_triage 2019-01-20 20:32:23 UTC 
Since the issue can't be verified on -stable and there is a good chance it has been fixed over the years I'm closing this bug as "Overcome by Events".

Feel free to re-open if it's reproducible on recent versions of FreeBSD.
