Most recent kernel where this bug did not occur:2.6.16 Distribution:Gentoo Hardware Environment:Toshiba Portege 3440CT Software Environment:pcmciactl-013 Problem Description: When suspending to ram (ACPI S3), resume does not work if a PCMCIA wireless network card is inserted. The card I'm using is a Compaq WL110. When resuming, the system stalls with the "Linu" show on screen. Wireless card powers up (LEDs flash) but the LEDs indicate "uninitialized state", and the system never wakes up. If I take the PCMCIA card out of the socket, the system resumes normally. I can then re-insert the card and it works fine. DMESG output, where I first suspend-to-ram, then resume, and then yank the card out (allowing the system to resume) and then finally put the card back in. This also happened with 2.6.17-kernels. 2.6.16-series worked (and still works) fine.

Oh, and note: This also happens if attempting to suspend to disk - in this case it does not even get to suspend properly (stalls at the portion where system wakes up some devices to write the pages to swap partition - yanking the card works there as well)
Does rmmoding driver for your pcmcia card before suspend help?
I cannot unload the module directly, # lsmod Module Size Used by hostap_cs 63380 3 hostap 117956 1 hostap_cs pcmcia 29560 1 hostap_cs yenta_socket 28012 4 rsrc_nonstatic 13376 1 yenta_socket pcmcia_core 40656 4 hostap_cs,pcmcia,yenta_socket,rsrc_nonstatic # rmmod hostap_cs ERROR: Module hostap_cs is in use Saying "pcmciactl eject" before suspending makes things work. When resuming the card is reinitialized again. I'm also able to repeat the issue by simply using "pcmciactl suspend" followed by "pcmciactl resume". When I press enter on the resume command, system freezes - Physically ejecting the card and the system becomes responsive again. Dmesg output is pretty much idetical to the one I pasted earlier. # pccardctl suspend # dmesg -c hostap_cs: CS_EVENT_PM_SUSPEND printk: 284717 messages suppressed. wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK wifi0: Interrupt, but dev not OK printk: 4 messages suppressed. wifi0: Interrupt, but dev not OK # pccardctl resume # dmesg printk: 13 messages suppressed. wifi0: Interrupt, but dev not OK printk: 7 messages suppressed. wifi0: Interrupt, but dev not OK printk: 14 messages suppressed. wifi0: Interrupt, but dev not OK printk: 13 messages suppressed. wifi0: Interrupt, but dev not OK printk: 6 messages suppressed. wifi0: Interrupt, but dev not OK hostap_cs: CS_EVENT_PM_RESUME wifi0: card already removed or not configured during shutdown printk: 237713 messages suppressed. wifi0: Interrupt, but dev not OK prism2_hw_init: initialized in 5405 ms wifi0: prism2_enable_aux_port - timeout - reg=0xffff wifi0: prism2_enable_aux_port - timeout - reg=0xffff wifi0: valid PDA not found SWSUPPORT0 write/read failed: FFFF != 8A32 hostap_cs: Initialization failed pccard: card ejected from slot 1 wifi0: card already removed or not configured during shutdown wifi0: card already removed or not configured during shutdown
Is the bug still present in 2.6.22-rc3 and/or in the latest -git ?
Zarhan, Have you tested with current kernel.org (2.6.22+), is the problem still there? Thanks.
Rejecting due to the lack of response from the reporter.
