This impacts all Toshiba M2. A workaround: In /etc/system, add set uppc:uppc_unconditional_srs=0 The Toshiba M2 BIOS has a wrong "_PRT" ACPI table entry for the cardbus controller, which causes the insertion/removal interrupt routed to the wrong vector. In some other OS this is not a problem because they share all PCI interrupts (in windows it's IRQ11 on M2). But in current Solaris we try to balance the interrupt load, reducing the # of shared interrupts as much as possible. That's why the wrong "_PRT" causes the problem. Vincent.
