** Description changed: Binary package hint: linux-image-2.6.17-10-generic - system: Turion 64 MT-40 + system: a laptop with an amd64 CPU (Turion 64 MT-40) and a wbsd- + compartible SD-card reader (W83L518D) + 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. + with DMA memory allocation on amd64 platform. If the machine has a wbsd- + compartible SD-card reader, the module loads automaticaly and 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.

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.
