Subject: rcu_kthread hang on 3.0.0-rc1-next-20110602
Date: Sat, 4 Jun 2011 00:43:25 +0300	[thread overview]
Message-ID: <85F46CF9-5433-4623-91FC-9CD890082F69@gmail.com> (raw)

Hello!

After updating my debian squeeze box to 3.0.0-rc1-next-20110602 I'm experiencing a weird problem. If I run dmesg  the computer hangs for 15 minutes, and I cannot even login at this time, if I leave top (the top window updates very slowly, like every 5 minutes during this period) running I can see that the process rcu_kthread takes 100% CPU, the computer load average is at around 10.

I also sometimes get these disk errors in syslog:
Jun  4 02:01:39 midi3g kernel: ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6
Jun  4 02:01:39 midi3g kernel: ata1.01: BMDMA stat 0x44

Jun  4 02:01:39 midi3g kernel: ata1.01: configured for UDMA/66
Jun  4 02:01:39 midi3g kernel: ata1: EH complete

but for example the last time I got the hang, I didn't get this error, nor any other error for that matter.

The OS is installed on a CF-card. The computer is a eBox computer with VIA Nehemiah CPU, 256MB RAM.

what more information do you need? Or what more can I test?
