Is anybody else seen that or did I screw up my Kernel config ? cheers ps: I have tried tracing a few different drivers and they all trigger the same problem. --=20 balbi --GlnCQLZWzqLRJED8 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJTxqcAAAoJEIaOsuA1yqREYEUP/2hseJVmSQo2p4wpKj94DRtf I/z0uliawZcfjHT1dd1pZLB1M7LaVseMyMqBJEh+3EJ+f9dytI1Lhg/AdwfBGnON 1l0+euun8UbU8mPpiX24r8GelKGF4+du7aTLcdEKxRGQKwtWw7Rc34PRHrciH9Xk +SQNM7IrOea7qP/AKRFrI9IUMkKu/D9USAjt0/OkB2fFkHmRINSSv5ZtGzTvo/6a +ydBc3k+RrztBkGfuFTHNlNNsZci/Mz+8BmAATWYABSTj7SZiYVcXJp2WKQhOoHC P9DQa5u1zIySCRPcLmZCaReUQFbbBYQuGacSOaO7toBA698oZG+YdMWfl2e4hWN5 UUxbAdEk1JiXjWrutgr5qMN1LzI+908aQUlk59qpbNiNraJzEDSa+ftwnsy4dJzD cvCBpxoSSuH1Ba1jrXATR6JwkYGfpPQ2FpK/oXldJLokpRfZihchidrascXMj+QD WQAa1RycLfH5KSK4vsJoSCJr2YZQDC2c4Kz5la4Pn8dHYwEAYG/gdiFv+9SGV14M hFWqB7123UTFlX1W3UQmrM6V+Rnesxa7+0w9wE+tw4xLFbuCT/nVRBnPdtMLLC8p ICk6tr+qWd0Djk5rPFl791ympv2NQ+MwDd/f+g4YcBeYbaugR9Rd/Kd7gVMDjXmY I2d1nNMjvCvBlD69zjBQ =fzE5 -----END PGP SIGNATURE----- --GlnCQLZWzqLRJED8--
