I've noticed temporary ohci freezes during boot on my new nForce4 Ultra based computer. First I noticed it with 2.6.13, but it is still there with 2.6.14.1. I'm using vanilla from kernel.org. Kernel says: ... ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) ACPI: PCI Interrupt Link [LUBA] enabled at IRQ 10 ACPI: PCI Interrupt 0000:00:02.0[A] -> Link [LUBA] -> GSI 10 (level, low) -> IRQ 10 PCI: Setting latency timer of device 0000:00:02.0 to 64 ohci_hcd 0000:00:02.0: OHCI Host Controller ... (here all activity stops, something waits for about 5 minutes) ... ohci_hcd 0000:00:02.0: new USB bus registered, assigned bus number 1 ohci_hcd 0000:00:02.0: irq 10, io mem 0xfebff000 hub 1-0:1.0: USB hub found hub 1-0:1.0: 10 ports detected This behaviour is pretty random, 90 % the boot attempts is fluent, but I've already experienced four subsequent occurences. I'd say it's much less frequent with 2.6.14, but it is still there. I'd be more than happy to help to debug this mystery.
Is this still present with 2.6.16-rc3?
I'm currently running 2.6.15.2 and haven't seen this freeze for some time, so it is hopefully gone. As it is hardly reproducible, consider this issue closed. Should it reappear, I'll just reopen.
Ok, closing, thanks.
