[Bug 38856] Re: [dapper] Soft lockup related to yenta IRQ handler

[Tero Karvinen]

To sum up, I am using "noapic irqpoll" as my default boot options. Works: CDROM, network, battery meter, cpu scaling. Broken: sound, suspend-to-RAM, external display. 

I have not tried "dist-upgrade" with the installation I am using now, because that's what broke it last time. 

I have testing notes on different parameters, to sum them up:
Ubuntu Dapper Flight 6 i386 Install CDROM
Compared to default parameter used in isolinux.cfg:
- Without any parameters: complete freeze on "Uncompressing Linux... Ok, booting the kernel. "
- With "noapic", boots past "booting the kernel", but does not find CDROM or network (my notes below. I will only attach photos if they are needed)
- With "noapic irqpoll" boots and finds peripherals
- "nolapic" - complete freeze
- I was using pci=noapci before, but don't know if it had any effect

0819
Booted from cd, boot menu:
- "F6 Other Options": added "noapic"
Computer booted past the "booting the kernel. "
Some text was briefly displayed (PICTURE 0821), written
by hand: "PCI: Cannot allocate resource region 7 of
bridge 0000:00:1c.0", similar for 8, 9.
"vt: argh, driver_data is NULL !"
"Trying to enable the frame buffer..."
"INFO: kbd-mode: setting console mode to unicode"
"[!] Choose language" was displayed.
- English
"[!] Choose language" "Choose your location:"
- other: Finland
Jumped to Finland by pressing "F" a couple of times
"[!] Select a keyboard layout"
(Default is American English, bug already filed)
- "Select from full keyboard list", "Finnish"
(press F to jump to Finnish)
0826 "[!!] Detect and mount CDROM"
"No common CD-ROM drive was detected. " (PICTURE 0827)
This is related to boot paramaters as described in
http://www.iki.fi/karvinen/acer_travelmate_3004wtmi_with_linux_notes.html
Alt-ctrl-F4 (PICTURE 0828)
Rebooting with alt-ctrl-del...

0829 boot from "Flight 6 i386 installer"
F6, "nolapic", enter
Freeze on "booting the kernel. "
Shut down with 5 s press on power button.

Would you like me to try the current installation also with "noapic nolapic pci=noacpi irqpoll"? As it has "noapic irqpoll" in it, it will probably work. Do you want some logs about it?
