Hello all, I have a thinkpad X41-tablet which uses the linuxwacom serial drivers. The tablet works perfectly when the laptop first boots, but does not work at all after resuming from sleep. I posted to the linuxwacom list but think that the problem might be more general in how acpi resumes the serial ports. As suggested here: http://www.thinkwiki.org/wiki/Installing_Ubuntu_6.10_on_a_ThinkPad_X41_Tablet I have added a script to resume.d which calls the setserial command: /bin/setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig >From looking at how Ubuntu at least stores the serial configurations, I think that the above is redundant. If I try to run the above command from the command line after resuming from sleep I get: Cannot autoconfigure port: Device or resource busy If I try to cat /dev/ttyS0 after the resume, all my trackpoint and keyboard die, no Ctrl-Alt-Delete etc. I have to cold reboot the system. I have tried > /dev/ttyS0 As was suggested on a tread in this list to about a serial console, but that does not revive my tablet. Also added the above line to the resume.d script I wrote, but this does not work. Any ideas of what I could do to revive this serial port? Or if you think I am completely on the wrong path, or am posting to the wrong list, please let me know. Thanks for the excellent work on the acpi infrastructure. I can tell you that daily use of a laptop has become much more pleasurable thanks to you. -- Marco - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
