I don't know. I expect Martin will know. The serial number range you reported is ISO week 19 of 2010. I don't have the affected serial number range for the XO-1.5 WLAN ESD problem. I do have part of the range identified, but not the full range. That's why you should wait for Martin to respond. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Trying with two that I have here, I get the same error: SHDCI: Error: ISR = 8000 ESR = 1 Command Timeout Stopping Selftest failed due to abort The firmware was: Q3A50 A3A36 After upgrading the Q3A50 one to Q3A62, I get slightly different output from the WLAN test: SDHCI: Error: ISR = 8000 ESR = 1 Command Timeout, Command reg: 50a Mode reg: 0 Arg reg: 0 Recent commands (decimal): 0 5 Stopping Selftest failed due to abort The serial numbers are: Make sure you talk to Martin about this. devel@lists.laptop.org tends to be focused on development discussions rather than deployment support.

The wireless card did not respond to commands. Normally a card will respond to commands. Speculation as to cause: (a) open circuit, (b) short circuit, (c) damaged card, (d) damaged host. It would require further analysis by Martin. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
