--- Comment #10 from Bruno <bonbon...@internet.lu> 2009-04-15 17:35:51 --- In reply to comment #6 Adding printk() right after each assignment of kt1 and kt2, showing their respecitive value the kernel does not stall... I will try moving around the printk's hopefully getting some more insight (looks like inserting some delay - which printk definitely does - helps get the kernel to boot). Here a small log extract around the TSC marking: [ 6.679978] calling initialize_hashrnd+0x0/0x20 @ 1 [ 6.682232] initcall initialize_hashrnd+0x0/0x20 returned 0 after 4 usecs [ 6.685826] acpi_idle_enter_simple(): kt1 = 1239823286526093114 [ 6.688120] acpi_idle_enter_simple(): kt2 = 1239823286528384540 [ 6.690371] acpi_idle_enter_simple(): kt1 = 1239823286530635735 [ 6.695144] acpi_idle_enter_simple(): kt2 = 1239823286535411036 [ 6.697328] Marking TSC unstable due to TSC halts in idle [ 6.699588] acpi_idle_enter_simple(): kt1 = 1239823286539851942 [ 6.702067] acpi_idle_enter_simple(): kt2 = 1239823286542331873 [ 6.704466] acpi_idle_enter_simple(): kt1 = 1239823286544730781 [ 6.707222] acpi_idle_enter_simple(): kt2 = 1239823286547487137 [ 6.709393] ata1.00: configured for UDMA/100 [ 6.711502] async_waiting @ 743 [ 6.713593] async_continuing @ 743 after 0 usec [ 6.715792] scsi 0:0:0:0: Direct-Access ATA FUJITSU MHT2060A 006C PQ: 0 ANSI: 5 [ 6.718059] sd 0:0:0:0: Attached scsi generic sg0 type 0 [ 6.720216] initcall 2_async_port_probe+0x0/0xc0 returned 0 after 5545494 usecs [ 6.722325] calling 4_sd_probe_async+0x0/0x250 @ 743 [ 6.724565] async_continuing @ 750 after 5545210 usec [ 6.726893] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input4 >From this I could guess that without the printk's async_waiting could be bitten by the timing issue and thus causing the hang (just a guess, to be verified!) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
