Hi!
Today I was looking into the output of "ps aux" and I saw an interesting line:
| Code: | USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 7523 0.0 0.1 2856 948 ? D 14:49 0:00 hald-addon-storage: polling /dev/hdc (every 2 sec) |
As far as I know, state D shows that the process is waiting for some I/O action by the kernel. So something with my cd-rw drive doesn't seem to be ok.
A "dmesg | grep hdc" shows:
| Code: | ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
hdc: CD-RW CR52, ATAPI CD/DVD-ROM drive
hdc: ATAPI 40X CD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)
hdc: request sense failure: status=0x51 { DriveReady SeekComplete Error }
hdc: request sense failure: error=0x04 { AbortedCommand } |
Because I have seen also a "lost interrupt" error one time, I checked my IRQ configuration. But the content of /proc/interrupts looks ok for me:
| Code: | CPU0
0: 3069741 XT-PIC-XT timer
1: 5651 XT-PIC-XT i8042
2: 0 XT-PIC-XT cascade
5: 381590 XT-PIC-XT ohci1394, ehci_hcd:usb1, ohci_hcd:usb2, EMU10K1, bcm43xx, eth0
7: 10 XT-PIC-XT parport0
8: 2 XT-PIC-XT rtc
9: 0 XT-PIC-XT acpi
11: 467760 XT-PIC-XT sata_sil, ohci1394, ohci_hcd:usb3, bttv0, nvidia
12: 4 XT-PIC-XT i8042
14: 173906 XT-PIC-XT ide0
15: 59617 XT-PIC-XT ide1
NMI: 0
ERR: 0 |
After this error occurs, I can not use my cd drive any more. Every process that tries to access, gets the D status and doesn't react anymore.
I also tried to reset the drive using "hdparm -w", but that didn't work.
Have you got an idea, what could be the problem here? Do you think it's a hardware defect or is it caused by wrong configuration?
Some further information that could be useful:
The problem occurs not during startup but after the computer ran for some minutes.
Kernel-Version is 2.6.22 (gentoo-sources).
There is no CD in my cd drive.
I've got a mainboard with NForce2 Chipset.
Please let me know, if you need further information. I would be happy, if someone could help
