Hi all I can confirm this bug occurs on the Toshiba Satellite A30 Laptop also.
The bug still exists for me in a fully patched 9.04 installation as of about 30 minutes ago. The machine is a P4 Mobile, Intel 82852 Chipset. As above the problem is resolvable by passing nosmp or nolapic to the kernel. I de-compiled the DSDT as per the above instructions and found 3 errors, 10 warnings reported, compiling a patched DSDT from http://acpi.sourceforge.net/dsdt/view.php?id=907 with iasl and using that at boot also fixes the issue. If it will help resolve the bug, I can provide logs of lspci, dmesg etc If this is believed to be a separate bug due to the hardware/manufacturer I also happy to raise it separately. ** Bug watch added: xxx ACPI support not a bugtracker #907 http://acpi.sourceforge.net/dsdt/view.php?id=907 -- System freezes during boot, unless I hold a key down https://bugs.launchpad.net/bugs/272247 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
