I turned on taskfile io on my last kernel, and had some stability problems. This is ia32, all ide but with ide-scsi. I experienced severe performance disruptions followed by what appeared to be a system hang twice. Before that, I was recieving an "hdd: lost interrupt" message every few hours, and the system felt sluggish. (The ide-scsi device is hdc, not hdd.) I have not had these problems with a kernel compiled without taskfile io. Is this a known problem? I can provide more information if it would be helpful. I also got the following, which looks like what Nick Evgeniev reported May 24 (2.4.19-pre8 ide bugs). Andre said to him > Obviously you have not enable taskfile IO, if you have then you have my > attention. As I had enabled taskfile IO, I figured I'd mention this: 11:42:29 bug: kernel timer added twice at c01b0107. c01b00b8 T ide_set_handler c01b0110 t atapi_reset_pollfunc 11:45:35 scsi0 channel 0 : resetting for second half of retries. 11:45:35 SCSI bus is being reset for host 0 channel 0. 11:45:35 hdd: ide_set_handler: handler not null; old=c01b0110, new=c01b1474 c01b0110 t atapi_reset_pollfunc c01b1474 T task_in_intr 11:45:35 bug: kernel timer added twice at c01b0107. 11:47:19 kernel: scsi0 channel 0 : resetting for second half of retries. 11:47:19 kernel: SCSI bus is being reset for host 0 channel 0. 11:47:19 kernel: hdd: ide_set_handler: handler not null; old=c01b0110, new=c01b177c c01b0110 t atapi_reset_pollfunc c01b177c T task_out_intr -- Paul Cassella - 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/ | ||||||||||||
