Hmm. It breaks booting on my quad, I finally got around to testing without this patch and it turns out that it caused the boot failure I reported in another mail. This is with v2.6.23-6623-g55b70a0, a clean tree boots fine but with these two patches applied and configured in it fails during boot, hanging at some point, apparently when userspace is entered. On the other hand, it is fine with my original version. I'll have to find some time to check the differences hunk by hunk I guess. johannes --=-RWzIvSHN54G1IA7Dc+Kg Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIVAwUARxynCqVg1VMiehFYAQLMww/+KS3a+txd7f1X9LgQ2FeI/XvoX813cMd9 rNxKylgMH8eL30aYtOu927UjZr7H+trwbU1UQAkOsP+baiGiXiejPfxVXW1xeN74 SHrQGaWQBi9EmuO0E1Nl7/HJtF8TQiUyfGTfdhFoeV9i8XLFSkKyNwBPFxsO/UTT qkleN1IN79N3XxyhPXcv6gjAAdxB1rr+yfrx/e6v1oSL4tcnYH87BTQkUCKVHgNc fkdFX8oimx1lTHjWY+kplr0l/T/wpHoMRvj3pzCeTlrlIek4A2bVmvposatleHeJ R7yIxSY0QBs6bP1nupmQCQHaS2FWE4d9kxsCH1nTXQ5pXrK8TG3+XF9cEuh+1t/5 fI9J7DrO6j8Hrfr9p40HZt4BW20dxJ7ui5x7kUM3laMS4SSsWXJJ0gvKzHUeFTxb 0sWMXPDo7nUOK/zg0j3N9TfabvmQ6KM+xNaLpU9XeuoilTIDc+huoFumODMKQwWC 3dCn8jgfOl+aIGMXAZ0+llkCN4ibrxZzry7nhXqxcBRyXbGcVDHsAk8w5ndlx2ca KflRo9uGVykPUzVPCJ7HV3ziiPsI5vyboGMVI9IwGOm2Z9pjnFMCgAJgE6ZDf9X0 7UQXNx+TeU2t7b5SPtvldsXRziJLMPAwpgr6uuJG53t/+n6/pG0fefRgIHbJl8PZ nEk5Ek4j5fc= =U/0y -----END PGP SIGNATURE----- --=-RWzIvSHN54G1IA7Dc+Kg--
