[PATCH 0/3] blkio: IO controller stats
The following series implements some additional stats for IO controller. These stats have helped us debug issues with earlier IO controller versions and should be useful now as well. We've been using these stats for monitoring and debugging problems after the fact as these stats can be collected and stored for la... 1 Apr 2010 19:07

Hi, a long time ago I used to use the binary only pwc driver; I noticed support is in the kernel now for (pwc)-based Logitech Quickcam Pro 4000 but, it doesn't work: [ 78.866729] pwc: Wrong size (67108864) needed to be len_per_image=462848 or total_size=925696 ...

[PATCH -v2] ibft, x86: Change reserve_ibft_region() to find_ibft_region()
So arch code could decide the way to reserve the ibft. And We should reserve ibft as early as possible, instead of BOOTMEM stage, in case the table is in RAM range and is not reserved by BIOS. move that just sfter find_smp_config() Also when CONFIG_NO_BOOTMEM=y, We will not have reserve_bootmem() anymorea... 1 Apr 2010 18:00

2.6.31 regression: programs crashing after a couple of days of uptime with hibernation
Hello, with kernel 2.6.30, I can have uptime of more than a month on my desktop PC (with hibernation). It's impossible with 2.6.31. After 1 to 3 days, processes that were running during hibernation (e.g. konsole, kwin, kicker, xorg) start to crash randomly in very weird ways. The kernel itself does not seem to cra... 10 Apr 2010 17:54

[PATCH] USB: pxa27x_udc: use four bits to store endpoint addresses
Endpoint addresses on pxa27x can be programmed as 1-15, but since only three bits were being used to store the endpoint number it was possible to overflow.
