[Kernel-packages] [Bug 362875] Re: rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset
I have experienced this bug on a non Ubuntu system for some time. I spent some time comparing the SparkLAN DPO driver source with the main line kernel driver source and tried a couple of changes. 1) There were some places missing a lock (this change did not affect this bug, however). 2) The DPO driver performed the 32-bit register writes as two 16-bit single write commands instead of one four byte multi-write command. I suspected that this might lead to race conditions setting the registers (not atomic) which was causing the Wi-Fi chip to hang. I thought it possible that the Wi-Fi chip firmware might buffer the two 16-bit single writes and then perform a single 32-bit write to the register, thus making it atomic. I asked SparkLAN about this, but received no reply. Note that the DPO driver performs the 32-bit register reads as a single four byte multi-read, just like the main line kernel driver does. I tested the following patch and the problem went away, either because it fixes the issue or it changes the timing to cover it up. Perhaps a distinction without a difference. ** Attachment added: "rt2x00usb.pat" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/362875/+attachment/4957754/+files/rt2x00usb.pat -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/362875 Title: rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset Status in linux package in Ubuntu: Confirmed Status in rt2x00 package in Ubuntu: Confirmed Bug description: Binary package hint: linux-firmware Dear friends, [24225.012753] phy2 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x308c with error -71.

[Kernel-packages] [Bug 1374965] Re: nvidia-setting crashes on startup
The bug appears to be a crash when unloading the vdpau library, either via a dl_close() or dl_fini() call. It also affects any application using the vdpau library, such as mplayer and mythfrontend. A backtrace from mythfrontend follows: mythfrontend crash details: *** Error in `/usr/bin/mythfrontend.real': free(): invalid pointer: 0x7ffe734bc623 *** Program received signal SIGABRT, Aborted. 0x73352bb9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 56../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.
