I was browsing the changelog for 2.6.21-rc2: http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.21-rc2, and saw a possible fix for this issue. Commit: e2f8fb72144a9f38d44ccf3f939e939392eda659 says: "sata_sil: ignore and clear spurious IRQs while executing commands by polling sata_sil used to trigger HSM error if IRQ occurs during polling command. This didn't matter because polling wasn't used in sata_sil. However, as of 2.6.20, all IDENTIFYs are performed by polling and device detection sometimes fails due to spurious IRQ. This patch makes sata_sil ignore and clear spurious IRQ while executing commands by polling."
I haven't tried this new kernel, but could if that is necessary. -- Sata Drive Not Detected https://launchpad.net/bugs/81595 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
