Bug Description
In order boot Ubuntu in a Toshiba M30X, you pass acpi=off to the kernel. The
problem is in the pcmcia support. I found the solution here:
http://
"After some ugly printk-based debugging in the Linux kernel, I found that the
0x800-0x8ff IO port range being probed by the pcmcia support was causing the
machine to hang. After excluding that range, pcmcia starts up fine. I didn't
bother trying to narrow it down to the minimal port range that can be excluded,
so if anyone wants to do so, just know that the problem starts right at 0x800."
To post a comment you must log in.
Kernel team: should we exclude this range by default in pcmcia-cs, or try to fix
the kernel?
