Bug#302001: kernel-image-2.6.8-2-686: clock breaks after inserting uhci-hcd module
Package: kernel-image-2.6.8-2-686
Version: 2.6.8-13
Severity: important
Hi,
Short version: After modprobe uhci_hcd, the clock seems to be broken: It
loops in 5 seconds and has some weird jumps approx. an hour away and
back. From then on, the system is unusable, as most applications simply
don't run anymore. In /var/log/messages, I get this:
Mar 29 16:37:11 localhost kernel: USB Universal Host Controller Interface driver v2.2
Mar 29 16:37:11 localhost kernel: ACPI: PCI interrupt 0000:00:1d.0[A] -> GSI 16 (level, low) -> IRQ 177
Mar 29 16:37:11 localhost kernel: uhci_hcd 0000:00:1d.0: Intel Corp. 82801DB (ICH4) USB UHCI #1
Mar 29 17:48:43 localhost kernel: uhci_hcd 0000:00:1d.0: irq 177, io base 00001800
No, I didn't really wait over an hour here. After the third line, I
waited for maybe 3 minutes, after that, the 4th line appeared.
Long version: I first encountered this bug after an Ubuntu Warty
installation some months ago: The system crashed randomly after some
hours (never more then 20 or 25). Before that, it ran SuSE with a 2.4
kernel, which never locked up this way. I was able to reproduce this
with Knoppix 3.7 and an up-to-date Sarge. It took me a long time to track
this down to the uhci_hcd kernel module. I blacklisted it in hotplug
and discover, so that it doesn't get loaded at boot-time. This leads to
a stable system. After loading uhci_hcd manually using modprobe, the
system locks up after some hours (well, the clock goes crazy, which
practically breaks the system). Sometimes, it happens immediately after
modprobing the module, so that /var/log/messages gets an entry as shown
above.
I don't really know how to debug this further, but it renders the system
unusable, as soon as I want to use a 2.6 kernel and the uhci_hcd module.
I'll attach the output of lspci -vv, maybe this helps somehow.
Thanks for considering.
Martin
