BUG: soft lockup - CPU#1 stuck for 61s! [khubd:267]

[karlrt]

i think this has something to do with my internet connection over a 3G network, i just got it yesterday, tried it, and it worked well for an hour, after that it froze everything, i had to hard reboot (not even print-REISUB worked)

Hi, thanks for reporting this. It looks to me this might be caused by recent regression in usb serial code. And there are many fixes been merged recently. Could you please test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds. Thanks.

i have to admit this kerneloops never happened again since. Perhaps it is fixed by some of the fixes. Honestly, i have no idea how to reproduce it. I am still working to get the 3g modem right with karmic, but i never go a freeze again.

Hi Karl,

Could you please let know the output of 'uname -a' here so that we know which specific kernel package fixed this problem? Thanks.

since i reported this bug i did alot of kernel updates while karmic was evolving, so i am not quite shure which of those solved the bug...

[Eric Miao (eric.y.miao)]

OK, so I'll just close this bug as is.
