Bug Description
Binary package hint: linux-source-2.6.22
On a Toshiba M200 Tablet PC, the integrated serial-line Wacom tablet interface locks up under the 2.6.22 kernel on Gutsy when returning from a suspend or hibernate.
I have verified that the serial settings the device file (ttyS0) are exactly as they were before reboot; the interface is mapped to the same location, same IRQ, and uart. The /sys filesystem reports in it's pnp information that the device is at the same location as it was before suspend. However, attempting to access the /dev/ttyS0 device causes the kernel to return a LSR Safety Check Engaged message.

Exactly the same problem here on a Toshiba Portege M400 tablet, running Gutsy i386 (generic kernel).
