 Posted: Sun May 01, 2011 10:15 pm Post subject: SSD drive making system slow |
 |
|
I got unknown problem with SSD drive it has Gentoo installed on it. The problem is - when PC not in use( system idle), after back to normal, decreased performance occurred, e.g. gnome interface become running slow, video playing slow, and games which runs from WINE same story.
just for test i have installed Ubuntu 11.04 and left PC idle for night then I started to test interface, movies and Games- everything was normal. But when i mounted partition on SSD drive- all became slow and dmesg has these lines afterwards:

And after that - all slow again. To back system to normal state i used to reboot it. And the most biggest problem - upper mentioned lines used to appear sometimes while system boots and then -complete hangs.
I don't know what to do - more likely i need shift to normal HDD, but not so desirable... |

| Can you reproduce the problem with an untainted kernel? Does the problem go away if you use the irqpoll option as the output suggests? |

i can't decipher your dmesg but i can tell you how i set up my ssd
do you have the discard option in fstab? for trim
| Code: | /dev/sda2 / ext4 noatime,discard 0 1
/dev/sda3 /home ext4 noatime,discard 0 0 |
also when configuring my kernel i use i/o scheduler = noop
my demsg

Tainted kernel means that i have proprietary drivers installed e.g. nvidia, of course, i can uninstall its and try again.
Full dmesg http://pastebin.com/PzBtyj1c You can found that same bug occurred down, but also involves IRQ 17
I didn't put any special settings for SSD, it configured like ordinary drive
| Code: |
UUID=6516f268-6c7a-438d-9484-ae7b3577e940 /boot ext4 noatime 1 2
UUID=89e821b4-2db5-43a2-85f2-f21dbdbe7567 / ext4 noatime 0 1
UUID=5e623e00-b433-4cc5-98eb-17e33568a0bf none swap sw 0 0
UUID=2ef70d09-ed88-4351-9999-8ec84733fe5a /home ext4 noatime 0 0
|
all partitions except /home located on SSD
current kernel config http://pastebin.com/z2Ruyg3s
I will do yours suggested settings and report result here afterwards |

i saw some interesting things googling 'disabling irq #16'
i'll let you look that up.
also you may look at kernel-seeds.org to compare against how your kernel is set up.

Well, i done these things-
1.put in fstab
| Code: |
UUID=6516f268-6c7a-438d-9484-ae7b3577e940 /boot ext4 noatime,discard 1 2
UUID=89e821b4-2db5-43a2-85f2-f21dbdbe7567 / ext4 noatime,discard 0 0
UUID=5e623e00-b433-4cc5-98eb-17e33568a0bf none swap sw 0 0
UUID=2ef70d09-ed88-4351-9999-8ec84733fe5a /home ext4 noatime 0 0

2. then enabled noop as default scheduler
CONFIG_DEFAULT_NOOP=y
CONFIG_DEFAULT_IOSCHED="noop"
full config http://pastebin.com/XfM0RxJf
3. added irqpoll to grub2 kernel options
GRUB_CMDLINE_LINUX_DEFAULT="quiet irqpoll rootfstype=ext4"
And... alas, again happened:
| Code: |

After searched "disable IRQ16" , didn't find any exact solution how to handle this error.
For now i have disabled all non essential hardware in BIOS, because i found that few devices uses one IRQ16.
This one before disabling:
| Code: |
16: 836485 0 0 0 0 0 0 0 IO-APIC-fasteoi xhci_hcd:usb4, eth0, nvidia
|
and after disabling Firewire, first Realtek network card , USB3.0, Bluetooth
| Code: |
16: 12375 0 0 0 0 0 0 0 IO-APIC-fasteoi nvidia
|
Till now nothing arise, will keep it more to make sure... |
