Subject: Cannot open /dev/mem

Message-ID: <4AA21AED.4030305@sil.org> (raw)

In looking at dmesg this morning, I noted the following section:

[  853.529553] ACPI Exception (thermal-0538): AE_ERROR, ACPI thermal trip point state changed
[  853.529558] Please send acpidump to linux-acpi@vger.kernel.org
[  853.529578]  [20080926]
[  855.757168] usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd hp rqt 128 rq 6 len 255 ret -110
[  857.665382] ACPI: Transitioning device [FAN0] to D3
[  857.665388] ACPI: Unable to turn cooling device [f6c152a0] 'off'
[  860.757203] usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd hp rqt 128 rq 6 len 255 ret -110
[  866.561178] usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd python rqt 128 rq 6 len 255 ret -110
[  871.561128] usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd python rqt 128 rq 6 len 255 ret -110


So, in response to the second line quoted above, I'm sending you the following:

~$ acpidump
acpi_os_map_memory: cannot open /dev/mem

I'm not sure what that means, but I hope it helps. fyi, I was plugging in my usb printer, which wasn't working correctly, which is why I was in dmesg.  In case that matters.

Grace,

Kent Rasmussen
