With previous kernels the bug showed up after each reboot. Now, when booting the patched kernel everything is fine and there is no longer any suspicious iowait! Do you have an idea why this problem appeared in 2.6.24? Did somebody change the ext2 code or is it related to the changes in the scheduler? regards, J?rg -- PGP Key: send mail with subject 'SEND PGP-KEY' PGP Key-ID: FD 4E 21 1D PGP Fingerprint: 388A872AFC5649D3 BCEC65778BE0C605 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
