Public bug reported: Binary package hint: linux-image-2.6.17-10-generic
system: Turion 64 MT-40 OS: Ubuntu 6.10 server x86_64 kernel: linux-image-2.6.17-10-generic_2.6.17-10.33_amd64.deb wbsd SD-card reader driver (CONFIG_MMC_WBSD) has some severe problems with DMA memory allocation on amd64 platform. It causes kernel (linux- image-2.6.17-10-generic_2.6.17-10.33_amd64.deb) to oops and in many cases hangs the machine. This is due to the fact that the original author wrote the driver for ia32 and still didn't port it to amd64. Here is the link http://lkml.org/lkml/2005/9/25/95 where he aknowledges it. Also, see a relevant part of my dmesg in the attachment. While it is desirable that the default kernel includes as many hardware drivers as possible, it is also important that the default kernel boots at all on any machine ;). The solution is: exclude wbsd.ko (CONFIG_MMC_WBSD) from any linux- image*_amd64 kernel. ** Affects: linux-source-2.6.17 (Ubuntu) Importance: Undecided Status: Unconfirmed ** Description changed: Binary package hint: linux-image-2.6.17-10-generic system: Turion 64 MT-40 OS: Ubuntu 6.10 server x86_64 kernel: linux-image-2.6.17-10-generic_2.6.17-10.33_amd64.deb wbsd SD-card reader driver (CONFIG_MMC_WBSD) has some severe problems with DMA memory allocation on amd64 platform.
