Ok, the last -rc obviously wasn't the last one after all, since here's a new one. Enough changes that we needed another -rc, and the regression list isn't emptying fast enough either (probably because a number of people, including reporters, are vacationing). But this should in fact close a number of entries, so it's not all doom and gloom. The actual bulk of this all is a new UVC video driver for the standard USB Video Class specification. It's a new driver, so shouldn't cause any regre...

On Sat, Jul 5, 2008 at 5:53 PM, Jon Nelson I recently tried a bunch of stuff: Things that do not help: 1. adding nolapic_timer 2. adding either of acpi_skip_timer, acpi_use_time_override 3. with or without nolapic, adding acpi_serialize hangs the boot. Additional debugging: 1. adding apic=debug 2. earlyprintk=vga One time, I got far enough to see: Booting Initializing CPU #1 Stuck ?? Inquiring remote #1 ... ... APIC #1 ID: 01000000 ...

The bus_shift parameter in platform_data is not needed as we can tell the driver with the IOMEM_RESOURCE whether the ASIC is located on a 16bit or 32bit memory bus. bus_shift as a configuration parameter is confusing at best because sometimes it means "shift register number left by n bits", sometimes it means "shift 32bit register address right by n bits" (see asic->bus_shift = 2 - pdata->bus_shift ...). The htc-egpio driver uses a more descriptive bus_width parameter, but for drivers wher...

It's not the best way to deal with it, more just a workaround, and if it does help it should be reported because it indicates something else is wrong. The main downsides to disabling APIC is that all interrupts will be handled by one core and you'll end up with much more IRQ sharing. Disabling ACPI on modern systems tends to be a bad idea, you'll get no Can you post your dmesg from bootup with the controller/drive detection? --

From: Jose R. Santos <jrs@us.ibm.com> This patch mostly controls the way inode are allocated in order to make ialloc aware of flex_bg block group grouping. It achieves this by bypassing the Orlov allocator when block group meta-data are packed toghether through mke2fs. Since the impact on the block allocator is minimal, this patch should have little or no effect on other block allocation algorithms. By controlling the inode allocation, it can basically control where the initial search for n...
